Fix cts fail for android.autofillservice.cts.augmented

In the test we trigger the manual autofill request programmatically,
because the focus isn't on the field, we will not get the callback
from IME.
It would be better not to ask IME for inline request if the request
is manual and the view is not focused because it's a simpler/safer
approach and manual request without focus should be rare.
