evas/proxy - redraw proxy source properly.

evas/proxy - redraw proxy source properly.

This patch fixes the proxy drawing problem that source won't be updated in some case

If the image object is the one member of the smart that has the proxy,
the proxy(image part) won't be redrawed properly unless evas tries to draw the image object.
This can be heppend if the image object is inactive cause of some reasone(ie. outside of the screen)
So, the proxy object never can be never updated even the image part is changed.
Now let try to be active if the parent is both active and source object.

and revert previous change with regarded to a739716ceec531a2178ac3c0d59bc15b90bb9167,
that's no more required now.
