ecore_evas: don't unset animator_ran in idle_exiter to prevent the render freeze.

You could meet render freeze if you use the evas wayland_egl engine.
Because ee's animator could be ticked by the wl_frame done callback of
the ecore_wl2 even while ee is in the idle time.

Thus we should not unset the animator_ran value of the ee if ee's animator
is ticked while idle time.
