Bug 1411667 - Remove Spoon plugin references entirely. r=maliu

Spoon and some Gradle work allowed to run certain JUnit 3 test suites
locally.  At the time, running the various test suites was diffficult.
Fast forward, and it's easier to run these suites, and in general they
are only run in Android Studio.  This will only get better as we move
the background services tests into a separate module (Bug 1229149).
