Remove duplicate utility functions from the Travis CI test suite.
Review Request #11203 — Created Sept. 25, 2020 and submitted
On rbintegrations 2.0, the Travis CI test suite contained a duplicate
_create_repository()and a truncated overridden version of
_create_config(). This caused issues running unit tests, since
_create_config()would outright fail and the primary
_create_repository()(which has fixes coming in from release-1.0.x)
This was likely due to a bad merge. There's nothing in the overridden
copies worth keeping.
This change gets rid of those versions.
Unit tests pass when running against Review Board 3.0 and 4.0.
