[MOB-9995] Fix and enable Android UI tests (#271)

* Fix email `EditText` matcher in Android UI tests

* Close media projection dialog in Android UI Tests

I had to add UiAutomator for this as Espresso can't interact with system UI while UiAutomator does.
I also bumped the `minSdkVersion` to 18 as UiAutomator's `minSdkVersion` is 18 and we can't make it lower than one of our dependencies.

* Enable Android UI tests on CI

* Fix typo in invocation Android UI test method name

* Check for success dialog with UiAutomator
