Bigtable: update pom.xml to fail loudly when an invalid profile id is passed

[igorbernstein2]

Bigtable uses maven profiles for running integration tests. If the user mistypes the profile id, the test profile isn't activated and the build succeeds, giving a false positive result. This PR will just fail the build

Fixes #<issue_number_goes_here> (it's a good idea to open an issue first for context and/or discussion)
