ecore_evas: improve ecore_evas fallback animator logic for legacy case. 

In Enlightenment with internal window being WL window connected to the
X11 backend, you end up with the later requiring the former to tick, even
if the former do not have a proper animator source. To work around the
problem when there is one backend that is not providing support for
animator source, we do need to avoid switching on another window source
as they could be linked somehow and we can not know.
