ecore_evas_extn: initialize server handle on server deletion

Summary:
Since plug sends message by using deleted server handle (dangling pointer),
I could see glorious error message as below:

	*** ECORE ERROR: Ecore Magic Check Failed!!!
	*** IN FUNCTION: ecore_con_server_send()
	ERR<842>:ecore lib/ecore/ecore.c:729 _ecore_magic_fail()   Input handle pointer is NULL!
	ERR<842>:ecore lib/ecore/ecore.c:740 _ecore_magic_fail() *** NAUGHTY PROGRAMMER!!!
	*** SPANK SPANK SPANK!!!
	*** Now go fix your code. Tut tut tut!

Therefore, I initialized server handle on server deletion

@fix

Test Plan: create socket -> create plug -> destroy socket -> mouse move on plug area
