Subject: [PATCH] Fix crash in unit tests after TextEntryTestCase::Editable().

The class TextEventHandler added in r77057 (see #3901) setup an event handler
which wasn't disconnected when the handler was destroyed, which resulted in a
crash later as the window it was connected to continued to exist and generate
wxEVT_TEXT events.
