This changes the fingerprint resistance code to set mIgnoreXULSize and mIgnoreXULSizeMode even when there isn't yet a primary content container, if this is a browser window. It also removes some dead code and reorders some other logic wrt mIgnoreXULSizeMode to make it more obvious what that code is doing, and renames the containing method to distinguish it more clearly from some other Load...Attributes methods.
