Add output test for pg_dependencies statistics import

Browse source 
Commit 302879bd68 has added the ability to restore extended stats of
the type "dependencies", but it has forgotten the addition of a test to
verify that the value restored was actually set.

This test is the pg_dependencies equivalent of the test added for
pg_ndistinct in 0e80f3f88d.
