internal/gophers: remove unused Gerrit group UUID

Prior to CL 247240, the addPerson line for Tools Team included:

	"1080@62eb7196-b449-3ce5-99f1-c037f21e1705"

This was a "<account ID>@<instance ID>" format that isn't used much,
but is documented as one of the formats that gophers.GetPerson accepts.
It was interpreted as an email because of the '@' in the middle.

That CL meant to replace the email with the UUID of a Gerrit group,
but there's no explicit support for such entries, and it currently
gets misinterpreted as the Tools Team's name.

We're not yet sure how to best handle teams on the Gerrit side,
but remove the UUID for now since it's neither supported nor used,
to reduce confusion.

Add test cases to help future team entry changes have the intended
effect.

For golang/go#50723.
For golang/go#27631.
