- Tests what happens on foreground applications when a restriction (like
Data Saver or Battery Saver modes) is turned on (prior tests would
turn the restriction on *before* switching the app to foreground).
- Tests multiple restrictions simultaneously enabled.
Also improved existing code:
- Fixed background state check.
- Reused some common checks in helper methods.
- Retries checks for process state.
