Running the exact Instrumentation tests and robolectric tests will yield different result if databinding is enabled on library modules. Currently the same exception is not thrown for `app` modules.

Sample repo: https://github.com/malvinstn/Robolectric-Databinding-Lib/tree/master

To reproduce:

- Run `ConnectedMainActivityTest` = OK
- Run `MainActivityTest` = OK
- Run `ConnectedLibActivityTest` = OK
- Run `LibActivityTest` = Error
