Fix robolectric test error

jobService is moved to mainline module. It is not registered in
the system at the beginning, therefore getSystemService returns
null. Instead of getSystemService, directly create a JobSchedulerImpl
and mock getSystemService method to return the JobSchedulerImpl
instance.

Test: make RunSettingsRoboTests
