edje_entry: Fix crash on selection

Summary:
When text is selected, crash happens due to double free as rectangles are freed both in _sel_update
and _evas_textblock_selection_iterator_free hence removing free from _sel_update.

@fix T2910

Test Plan:
1. Launch elementary test
2. launch entry demo
3. select text
