Handle the case where a tester has access to 0 releases

[lfkellogg]

Also refactored the FirebaseAppDistributionTesterApiClient a bit while I was in there, to clean up the error handling and reduce the scope of the try-catch blocks in there, which were large, catching multiple exceptions of unclear origins, etc.

/test check-changed

I think this is only failing because of lint tests. If you run

./gradlew :firebase-app-distribution:googleJavaFormat locally, it should fix the check-changed

Also, you can run ./gradlew :firebase-app-distribution:check withErrorProne locally to see the result of check-changed.

Oh perfect, thanks for the tip! This also made me realize my google-java-format plugin wasn't enabled, all set now 👍
