Fix sizeToFit / sizeThatFits: logic

According to the UIView documentation, you should not override sizeToFit but rather
override sizeThatFits: and do the right thing in there. sizeToFit then calls
sizeThatFits: to do the dirty work of setting the frame.

It was unnecessary to grab the 0th subview, which is the internalTextView anyway.
Switch to layoutSubviews

It's safer to use layoutSubviews than to override setFrame:.
