extensions: prevent a crash on py3 when testing a bad extension minimum A `None` placeholder is populated for each missing component by `util.versiontuple()`, which could safely be used with `>` on py2, but not py3. I guess there's another hole here where if the string is entirely bogus (i.e no numbers), it will be treated as 0.0, and always load. But that's always been the case.
