Added tests for different combinations of subcharts & requirements.yaml

Added more tests to test following comibnations of subcharts and requirements.yaml
- [ ] subcharts not specified in requirements.yaml
- [ ] some subcharts specified in requirements.yaml while others should be picked directly from "charts\"
- [ ] all subcharts specified in requirements.yaml without alias
- [ ] subcharts specified in requirements.yaml with alias is already tested
