Return an empty list instead of null.
TextServicesManager#getEnabledSpellCheckerInfos() was introduced in
commit 4c7423735e60fdf521678becb1b382c4625aed4a
as #getEnabledSpellCheckersList().
Then, the following commit added SuppressLint("NullableCollections"):
commit d7f33cd6486e8df59fe71f0b4775ebb525637553
As this API has been introduced recently in Android S timeframe, I think
it's better to fix the API behavior before it's finalized.
