Dev: add simple automated UI test setup (#1027)

## Description
This PR is mostly a proof-of-concept for setting up automated UI
testing. The tests use Roboelectric so they can run without an emulator.
There is also a sample instrumented test for running on emulators or
devices for future tests.

It adds two basic automated UI tests for adding a server. These are sort
integration tests because they use the actual implementations for the
view model and services like `ServerRepository` and `JellyfinServerDao`.

Also, moves the bulk of `MainActivity`'s compose code into a function
for future tests.
