Clean up choose lock intent creation
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. Test: cd tests/robotests && mma Change-Id: I5ff033f459c33ec9980872a536b3996d89f2bbbb
