demandimport: fix a crash in LazyFinder.__delattr__ I was tinkering with `with hgdemandimport.deactivated()` wrapped around loading the keyring module, and got spew that seemed to be confirmed by PyCharm. But I can't believe we haven't seen this before (and phabricator uses the same pattern): ** Unknown exception encountered with possibly-broken third-party extension "mercurial_keyring" 1.4.3 (keyring
