OC\Files\Cache\Cache::get can return string|false|null, not just string|false.
- nextcloud/server#26270 added handling of false, but null is needed too.
- Well, or we change the default $resullt to false, but I'm not sure if that has other ramifications and the real need here is to simply catch situations where the cache source storage path is not valid for whatever reason

- only the media part of the mime type can be search, but not the full

Target case is photos app: when visiting the tags category, all systemtags
of the whole cloud are retrieved. In subequent steps the next tag is
requested until the browser view is filled with tag tiles (i.e. previews
are requested just as well).
With this approach, we incorpoate the dav search and look for user related
tags that are used by them, and already returns the statistics (number of
files tagged with the respective tag) as well as a file id for the purpose
to load the preview. This defaults to the file with the highest id.

In some scenarios (file not in cache, but partial data of it in the
object), Cache->get() might return an array, which leads to errors like
"Call to a member function getId() on array".
So check whether the returned entry is of type ICacheEntry before doing
operations on it in Cache->remove().

Directory entry file names are now normalized in getMetaData(),
getDirectoryContents() and opendir().
This makes the scanner work properly as it assumes pre-normalized names.
In case the names were not normalized, the scanner will now skip the
entries and display a warning when applicable.

The encoding check for file names is now happening the Scanner, and an
event will be emitted only if the storage doesn't contain the encoding
compatibility wrapper.
The event is listened to by the occ scan command to be able to display a
warning in case of file name mismatches when they have NFD encoding.

The scanner would not find a NFD-encoded file name in an
existing file list that is normalized.
This normalizes the file name before scanning.
Fixes issues where scanning repeatedly would make NFD files flicker in
and out of existence in the file cache.

Make sure that when a user copy a file from a directory they don't have
all permissions to a directory where they have more permissions, the
permissions are correctly set to the one from the parent taget folder.
This was caused by the ObjectStoreStorage::copyFromStorage using
the jailed storage and cache entry instead of the unjailed one like other
storages (the local one).
Steps to reproduce
+ Use object storage
+ Create a groupfolder with one group having full permission and another one
who can just read files.
+ With an user who is in the second group, copy a file from the groupfolder to
the home folder of this user.
+ The file in the home folder of the user will be read only and can't be deleted
even though it is in their home folder and they are the owner. In oc_filecache,
the permissions stored for this file are 1 (READ)
