Make it possible to debug failed hook imports via use of --traceback

Prior to this change, if a Python hook module failed to load (e.g. due
to an import error or path problem), it was impossible to figure out
why the error occurred, because the ImportErrors that got raised were
caught but never displayed.

If run with --traceback or ui.traceback=True, hg now prints tracebacks
of both of the ImportError instances that get raised before it bails.

# Here the following repository history is used for testing:
