Enable H407,H305,H307,E122 ignore E123

After bumping the hacking version to the 0.9.x series ignores were
added for several rules. This commit fixes the violations for a subset
of these rules and re-enables the checks.

E123 is ignored because this rule is ignored in the default pep8 by
default, due to a lack of consensus around it.
