[tests-only][full-ci]Refactor code to reuse code in ocis

[SagarGi]

Description

This PR adds some code adjustment (in core) so that the code can be reused in ocis (If any new implementation is done). Since as of now we are duplicating the same code in core as well as in ocis.

We have a favourite.feature feature in ocis where we have been duplicating code so for reference i have tried to reduce the code in ocis for the feature so that it uses code (resource) already in core (for reducing code duplication). Follow this PR owncloud/ocis#4492

NOTE: We can do like this instead of creating extra helper function to reuse then code from ocis. If feasible then we can go ahead and refactor where code duplication has been done.

Looks OK - let's merge this and we can see what the refactoring of oCIS local API tests looks like. We can adjust again if we need to...
