Fix for crash due to call to eina_error_set when bridge object is null

In some scenarios it's possible to call _bridge_object_unregister
function, when bridge object was not constructed, which resulted in
call eina_error_set and possibly crash. This patch adds an if check
for existence of bridge object.
