[Tests-Only] Add api trashbin tests

[phil-davis]

Description

This PR adds apiTrashbin bug verification scenarios.

The same as PR owncloud/ocis#489 and PR owncloud/ocis-reva#453

This enables future developers to be able to see the behavior in tests while they are understanding and fixing.

for some reasons some of these tests have been reported unexpectedly passing in my new PR: #1125

This PR is adding local bug-demo scenarios. It does not adjust expected-failures from core.

@ishank011 @labkode these scenarios might work better or differently after #1125 - I will rebase this...
