Repo API Broken in master

[GrahamCampbell]

$paginator->fetchAll($client->me(), 'repositories', ['all']) will throw:

Github\Exception\RuntimeException: If you specify visibility or affiliation, you cannot specify type.

This must have been broken somewhere between: 2.7.0...b716e03.

Hmm good catch. We can fix this by making the default value of the new parameters null and add some extra code in the method to unset the type value if visibility or affiliation is set?

What do you think @GrahamCampbell @hotmeteor?
