Fix ibus first keystroke goes two (#1886)

Browse source 
Calling `moveCaretToEnd()` when `richText` is empty will cause the first keystroke of
ibus-based input methods with candidates to goes double. For example, if you
type "a" it becomes "aa". This problem exists in many linux distributions.
When `richText` is empty, there is no need to place the caret, just return
as a workaround.
