Remove binder tests from AdapterServiceTest + unification

The binder is already tested in AdapterServiceBinderTest.java. I am
simplifying the test logic by not having to deal with the binder.

This is a base change for incoming change (maybe having a split file for
the AdapterServiceBinder ?)

Unification is required as all theses test will moved to a TestLooper in
order to have a constant reproducability and remove flakiness
