What's happening here is, setAlphabetKeyboard sets the
keyboard to AUTOMATIC_SHIFTED and updates the keyboard, then
restoring the keyboard old state sets it back to UNSHIFTED without
updating it. When we finally know what the correct value is,
we try to set it to UNSHIFTED, but since that's already the currently
recorded state, it skips updating the keyboard forever.

The solution is to avoid setting the shift state without updating the
keyboard.

This is not enough to really fix behavior with TYPE_NULL,
but it does make things a bit better.

It was possible that fetchNextTasks() would be called by multiple
threads concurrently.
If it happens, some tasks in the task queues might be ignored.

The PARAGRAPH type of span is dangerous, as concatenating
CharSequences that contain it may crash. We also don't use
other spans than SuggestionSpans, so we don't copy them.
