Fix the listener in the incremental service.

Summary: The listener doesn't function as intended. The previous
listener triggers for changes matching the given code or changes
matching the package, always returning the listened code, not
the changing code.

The end result is that logging will be disabled if there are any
changes for a data loader. An example can be seen when the
device is activated and a number of changes occur, resulting in
the disable logging flow.

With this change, we listen to all changes for a given package
name. This results in the listener being called with accurate
codes, which we can then filter for.

Test: Successful Build on master branch
Flag: EXEMPT small bugfix
