dispatch: disable demandimport for the --debugger option
Something in Python 2.7.9 or so broke the --debugger option with
ui.debugger = ipdb. I get the traceback below. There is some apparent
confusion with demandimport. This should be disabled anyway for the
--debugger option. The debugger must be imported right away, before
any other dispatch. There's no benefit in delaying the debugger
import.
This patch uses the demandimport.deactivated() context manager.
