Fix generated links for DiffCommit resources

Previously, the generated links for the DiffCommitResource and
DraftDiffCommitResource were being overridden by the resources for
the parent DiffResource or DraftDiffResource, respectively. Now,
only the files link is taken from the parent resource and the other
links are not overriden

Ran unit test.

Checked the links of a DiffCommitResource and saw that they were
correct.
