If you call flycheck-copy-errors-as-kill with a normal argument you will get the desired effect (list's first entry).

• C-u 1 M-x flycheck-copy-errors-as-kill will add the error id to the kill ring.
• C-u M-x flycheck-copy-errors-as-kill will add the error id and the message to the kill ring.
• M-x flycheck-copy-errors-as-kill will add the the error message to the kill ring.
