Workaround incorrect Uint deprecation message

The Uint deprecation warning suggested a system dependent type (UInt64
or UInt32) rather than UInt, due to this being a type alias.  Hardcode a
warning message for this rather common type, pending a more powerful
deprecation warning system.

ref #13227
