overriding onmousemove etc. then connecting doesn't work

[bill]

See test_deferredConnects.html for test case.

If you specify an onmousemove handler on initialization (or any deferred-connect event), and then later do a dojo.connect() on that handler, the dojo.connnect() won't be called.

(In [16926]) When specifying a deferred-connect handler (like onmousemove) as an initialization parameter, and then later doing a dojo.connect(), the connect wasn't working.

Problem was that the connection from the Widget.focusNode to Widget.onMouseMove() was incorrect; it connected to the actual function, rather than using the string "onMouseMove", so that the later dojo.connect() call, which replaces Widget.onMouseMove() with a dispatcher function, wasn't affecting what the Widget.focusNode connection was executing.

Fixes #8814 !strict.

(In [20395]) Apparently on IE8, a console.log() causes a mousemove event, and thus a console.log() on mousemove causes an infinite loop. So just print message on the first mousemove. Refs #8814 !strict.
