exactness: do not efl_del the evas

there is no need to do that, more than that. This is super dangerous,
the display and connection ptr of x are passed from ecore_evas to evas,
if you delete evas before ecore_evas, the later ecore_evas deletion will
destroy the x connection which calls some functions in evas, which is
already freed, which leads to a crash.
