Always verify PolyGerrit if bazel related files are changed
Always verify PolyGerrit if bazel related files are changed

Polygerrit was not verified, if Bazel related files were changed
outside of the polygerrit-ui directory except for the WORKSPACE
file. However, there are Bazel related files that are influencing
the build and tests of Polygerrit.

Thus, now if there was a change to a Bazel related file, the
Polygerrit UI will also be verified.
