We'll now clearly differentiate between cold / hot starts of HomeActivity.kt.
This is needed because Android will resend the original Intent which initially
started the Activity whenever it is restarted from the Recents Screen if the
activity is already destroyed at that time. So in the event that the activity
was before started with an Intent to open a webpage for example whenever the
activity is restarted from Recents it will receive the same Intent to open a
webpage even though that Intent has already been consumed.
Activity's onCreate() will only use the intent processors when the activity is
cold started so that we'll only initially act upon Intents configured for
different behaviors inside the app.
If the activity is destroyed while in background and opened from Recents it
will not act upon the original Intent which is now resent by Android.
Activity's onNewIntent() will be called to act upon a new Intent if the
activity is hot started since we are declared as singleTask and it now has the
responsibility to delegate various intent processors to consume that Intent.
This is how we can apply the new test runner to remove duplication.
This commit was generated programmatically with the following commands:
```
// Replace test runners with new one.

find app/src/test -type f -exec gsed -i "s/@RunWith(AndroidJUnit4::class)/@RunWith(FenixRobolectricTestRunner::class)/" {} +

find app/src/test -type f -exec gsed -i "/import org.robolectric.annotation.Config/d" {} +
```
Where gsed is the GNU version of sed installed via homebrew. After
running these commands, I need to manually clean up the following files:
- FenixRobolectricTestRunner
- LocaleManagerExtensionTest
