Follow-up from "Draft: Build tools"

The following discussion from !1390 (merged) should be addressed:

• @rhstone started a discussion:

  The value for R.string.tv_provider_authority has extra escapes. Take a look at gradleResValues.xml. Consider:

  resValue 'string', 'tv_provider_authority', "${rootProject.ext.appId}.tv"

  Same issue on line 74 for the debug config.

  Probably needs some more investigation to confirm there are no impacts from removing the extra double-quotes. Are the string/URI functions filtering the value at runtime?
