* [Android] Update header image for quick shortcuts and optimization
Optimizations done:
- Initialize leo and wallet controllers regardless if feature enabled or not. This is because at this point native is not guaranteed to be initialized to check the feature. Check for option visibility is done in `BraveRadioButtonGroupAdaptiveToolbarPreference` instead.
- Override `buildUiStateForStats` to avoid asserts on Brave specific options.
* Fix for tests
* Fix for JUnit tests
