Subject: [PATCH] Added initial test for AppDetailsRecyclerViewAdapter.

Doesn't do anything except create an app with no versions,
no donate links, anything like that, and ensure that the adapter
is able to create the view holders for each resulting item.

In the future we can beef this up to check more exotic conditions,
such as calling `updateItems(App)` with different apps, each
with different combinations of versions, donation links, permissions,
etc.
