pgAdmin III commit: Resolved an issue related enable/disable menu items

Resolved an issue related enable/disable menu items in Query Editor
specifically for Unity Desktop Environment.

wxWidgets was not able to identify the current focused control in some
cases, during certain event generation. And, that was resulting into
disabling the wrong menu items.
i.e.
Copy, Paste, Undo, Redo, Cut, Paste, Add/Manage favourite menu(s)

In order to resolve the issue, we will not consider the events
generated, but - no control gets focused, while enabling/disabling the
menus.
