PHOENIX-3426 Fix the broken QueryServerBasicsIT

For integration tests with MiniHBaseCluster, we have to
deal with multiple versions of protobuf on the classpath.
As such, it's easier to use the shaded artifact from Avatica
instead of re-shading that in Phoenix and trying to keep
the Phoenix classes off the test classpath.
