Changes to support unbundled ChooserActivityTest

 1. Assert the logging package name matches the one we read off of
 instrumentation at runtime, instead of hard-coding a package that will
 only match in one version of the tests.

 2. Set up infrastructure for UnbundledChooserActivityTest to disable
 part of the APS availability test that doesn't make sense in the
 unbundled version.

 3. Expose the name of an extra that we now need to use more widely.

 4. Disable a test that seems non-trivial to fix for the unbundled
 implementation. This could reflect a real issue with the unbundled
 behavior and should be addressed ASAP, but I don't want this to block
 ag/16516860 so we can at least get some baseline tests running.

Test: `atest ChooserActivityTest`. Also tested the unbundled version
(slightly modified from ag/16516860 based on the changes above).
