enventor: Fix to move scroller bar to correct position for find function

enventor creates a scroller instead of using entry's scroller for text
editor. This causes that the scroller bar moves to incorrect position
when a word is selected by find function. To resolve this problem, set
entry's cursor position before setting entry's select region.
