Fixes part of #40: Added bottom padding to Question Player

Before this PR more than 2 test cases were failing on espresso in QuestionPlayerActivityTest that were fixed by adding the bottom-padding which was also a requirement as per mocks.

But still 2 test cases are failing because of nested recyclerview for SelectionInputInteraction.

In both these tests we want to scroll to index=3 item of the selection_interaction_recycler_view but the scrolling is disabled because it's an item of question_recycler_view and in current code we cannot scroll to this specific position.

Output on Pixel 3 (5.56")

Output on Pixel 3 XL (6.3")

To fix this I have filed an issue #3370

@BenHenning @anandwana001 PTAL at the description and can you suggest something on how to fix these failing tests?

I will take a look at this by tomorrow.

@rt4914 per our discussion earlier in the week, is further input needed from me for this PR?

[BenHenning]

Hmm. I'm not keen on changing padding for the purpose of testing since that has real side effects for users. Do you have a before & after to demonstrate the effects?

Thanks @rt4914. LGTM.
