Subject: [PATCH] Remove bogus `{code}` attributes on `TraitImplMismatch`.

This makes no sense, and has no effect. I suspect it's been confused
with a `code = "{code}"` attribute on a subdiagnostic suggestion, where
it is valid (but the "code" there is suggested source code, rather than
an error code.)
