Previously everything lived in an inner class method of
SettingsRobolectricTestRunner. That method has now been turned into
a static method so that it can be called by other runners.

Test: robotests

Consolidated the many variants of ChooseLock*.createIntent, so that
it will take the same set of arguments.
Also modified SetupChooseLock*.createIntent to modifyIntentForSetup,
which will take the intent created by ChooseLock* and modify it for
use with setup.
