Remove 'Show' constraint from 'ReadId' constructor in 'Ident'

[Erik Hesselink]

I think we can remove the Show id constraint in the ReadId constructor of Ident. I removed it and nothing seems to break. I also don't remember why we have it. @bergmark Do you remember why we have this?

[Adam Bergmark]

Nope...

Hmm, then I guess after a last look at the history we should just remove it.
