originalTableContentInset not always set correctly.

[markst]

I'm using a translucent navigation bar in combination with auto setting content insets. Which means my top insets is often 64pt.

For some reason keyboardWillHide: gets called without keyboardDidShow:. I think this is an iOS9 thing & not investigated properly yet.

But this results in originalTableContentInset never being set & my content insets being set to zero within the keyboardWillHide: method.
