Different font on first item

[sbravotalero]

Issue Description

The first item appears with a different font than the others on iOS 11. This is how the appereance is being configured:

bar.appearance = TabmanBar.Appearance({ (appearance) in
appearance.style.background = .solid(color: .grey38)
appearance.state.color = .grey142
appearance.state.selectedColor = .signatureYellow
appearance.text.font = UIFont.Geograph.medium.ofSize(16.8)
appearance.indicator.isProgressive = false
appearance.indicator.color = .clear
})

@sbravotalero I believe that is due to the fact that Tabman has adjustsFontSizeToFitWidth enabled on the bar buttons. Would it be useful to make this behaviour configurable?

@sbravotalero just released Tabman 2 which should have resolved this issue and in general is hopefully a lot better! 😄
