Focus on search field EditText and launch keyboard when AutoComplete is opened

[langsmith]

This ticket is to track @jollygreenegiant's question/request (https://github.com/mapbox/mapbox-plugins-android/issues/1008#issuecomment-510541027) regarding making the search field focused when the autocomplete activity is launched so that they keyboard automatically comes up, rather than the user having to click in the box first.

This will be resolved when #968 lands. #968's https://github.com/mapbox/mapbox-plugins-android/commit/0c64cf98a75eb3cf3f0d4f3470ac56e1e9caab0d commit resolves this.

Is this still relevant? If so, what is blocking it? Is there anything you can do to help move it forward?
