efl_ui_pager: fix to delete component objects when pager is deleted

Pager creates Efl.Canvas.Rectangle objects when pager is constructed.
Since the parent of these component objects is evas, these component
objects are not deleted automatically when pager is deleted.
These component objects cause event block after pager is deleted.
(e.g. click event is blocked)
To resolve this issue, these component objects are deleted manually when
pager is deleted.
