Make the PushCreate test declarative (#11229)

Reduce the code duplication in the PushCreate test and switch
to a declarative format.

* Instead of explicitly creating the repository re-use functions from the other declarative tests and add comments
* Ensure that the test repository is deleted at the end of test
* Slightly reorder the sub-tests

Also reduce the code duplication in MergeFork and add some comments there too and make doGitCloneFail be self-contained.
