extensions: show traceback on load failure if --traceback flag is set
Before this patch, there was no handy way to investigate the reason why
extension couldn't be loaded.
If ui.debug is set, tracebacks of both "hgext.foo" and "foo" are displayed
because the first ImportError could occur at very deep dependency module.

test deleting .hg/bookmarks.current when explicitly updating
to a revision
$ echo a >> b
$ hg ci -m.
$ hg up -q X
$ test -f .hg/bookmarks.current
try to update to it again to make sure we don't
set and then unset it
$ hg up -q X
$ test -f .hg/bookmarks.current
$ hg up -q 1
$ test -f .hg/bookmarks.current

when a bookmark is active, hg up -r . is
analogous to hg book -i <active bookmark>
$ hg up -q X
$ hg up -q .
$ test -f .hg/bookmarks.current
