Revert "efl_ui_layout: call efl_del instead of efl_unref when text part does not exist"
This reverts commit cced5487c83c8f75e2ca40969f5749d5e6570228.
This patch was pushed just to silence warning without fixing the problem and doing
something that was incorrect (coupling an efl_del with an efl_ref).
