[DO NOT MERGE]Fix PermissionsHostTest#testNoResidualPermissionsOnUninstall is failing
on Baiji (and maybe other Android P based watches).

The failure is because the permission labels of certain permissions are
two long and thus get truncated in the UI. Therefore, the test can't
match them in the test.

It also tries to reduce flakiness in certain tests, such as
PermissionsHostTest#testDenialWithPrejudice23.
