extensions: changed to call extsetup() from extensions.loadall()

extensions: changed to call extsetup() from extensions.loadall()

previously uisetup() was invoked by extensions.loadall(), but
extsetup() was by _dispatch().

there's no need to split them because we have nothing to do
between uisetup() and extsetup().

this fixes issue1824 indirectly.
