base: App crash when select suggestion's length more than specified.

App crashed by catch IndexOutOfBoundsException which raised
by check span range when select suggested string.The root
cause is that the editor will truncate the suggested string

use the suggestion's original length.

Update the suggestion's real length after editor replace the
