inputMethod: Make set_surrounding() send also empty string

Browse source 
Empty surrounding text values needs to be sent to IBus engines
so that the engines know the focus is changed and the values are
updated.
Also InputMethod can forward the "require-surrounding-text" signal
from IBus engine to mutter.
