extensions: call afterloaded() with loaded=False for disabled extensions

If an extension was loaded but disabled due to a minimumhgversion check it
will be present in the _extensions map, but set to None.  The rest of the
extensions code treats the extension as if it were not present in this case,
but the afterloaded() function called the callback with loaded=True.
