iOS 10 issue with section titles

[chriscombs]

Seems like on iOS 10, if you give a Section a title, it is assigned to the default titleLabel of the cell, even if you have a custom header configurator set. This can lead to overlapping labels if you have a custom title label and aren't using the default one.

This seems to be an iOS 10 bug. I fixed it in a project by adding the following line in the headerConfigurator closure:

headerView.textLabel?.isHidden = true

We could do that in Sourcery, but I'm not sure that always hiding the default textLabel in the header is a good idea.
