fix filselector legacy cb call order and entry set - fix file,chosen

The visible bug for this issue is that the Elm External Video example
is broken:

elementary_test -to "ExtVideo"
The root cause is that the "file,choose" event of the
FileselectorEntry is (wrongly) not listed by the function:
evas_object_smart_callbacks_descriptions_get()
This evas functions is used in elm_external to forward all the widget
events to edje, but it cannot forward the "file,chosen" event because
it's not listed.
Thus the video test is not working for the lacks of that event.

I think the fix should be somewhere in elc_fileselector_entry.c, there
are some hacks there for the incriminated signal, but I don't know how
to properly fix.

I think the problem is in this function: (elc_fileselector_entry.c)
