Fix for a regression introduced in D9010.

The problem was that the previous code returned immediately which means baseReducer wasn't able to properly modify the state.

Not a huge fan of this solution but I saw this somewhere in the codebase. As an alternative, I can suggest:

1. Creating a separate reducer and running it in the same place - don't think is much better, will require the same assignment.
2. Creating separate reduce and moving this to lib.

Only 2 seem better than this, but don't want to put native-specific data in lib.

Using Redux DevTools make sure that logout is handled and data that needs to be cleared is cleared/set default where it needs to be.
