createrepo version check fails when version is missing

[ghost]

The version check for createrepo reads:

        ### If version < 0.4.6, then use the old createrepo behaviour
        if not createrepo_version:
            error(0, '%s: Version of createrepo could not be found. Assuming newer than 0.4.6.' % self.dist.nick)
        elif vercmp(createrepo_version, '0.4.6') > 0:
            groupfilename = 'comps.xml'

The message says "assuming newer than 0.4.6", yet it uses the pre-0.4.6 behavior.

I assume this should actually read:

        ### If version < 0.4.6, then use the old createrepo behaviour
        if not createrepo_version:
            error(0, '%s: Version of createrepo could not be found. Assuming newer than 0.4.6.' % self.dist.nick)
            groupfilename = 'comps.xml'
        elif vercmp(createrepo_version, '0.4.6') > 0:
            groupfilename = 'comps.xml'

So that the newer-than-0.4.6 behavior happens both when the version is not defined and when the version is actually greater than 0.4.6
