bug#45793: 28.0.50; Gnus cannot respool on nnimap

[Phillip Lord]

I cannot respool mail when using nnimap.

*Messages* reports:

Moving to nnimap: (2583)...
((NO (TRYCREATE) Mailbox doesn’t exist: mail.misc (0.001 + 0.000 secs) .))
Couldn’t Move article 2583: ((NO (TRYCREATE) Mailbox doesn’t exist: mail.misc 
(0.001 + 0.000 secs) .))
nnimap read 0k from localhost
nnimap-send-command: Buffer  *nnimap localhost nil  *nntpd**-510358 has no 
process

I think it comes from this code in gnus-summary-move-article:

  (gnus-request-move-article
            article                     ; Article to move
            gnus-newsgroup-name         ; From newsgroup
            (nth 1 (gnus-find-method-for-group
                    gnus-newsgroup-name)) ; Server
            (list 'gnus-request-accept-article
                  to-newsgroup (list 'quote select-method)
                  (not articles) t)     ; Accept form
            (not articles)              ; Only save nov last time
            (and move-is-internal
                 to-newsgroup           ; Not respooling
                                        ; Is this move internal?
                 (gnus-group-real-name to-newsgroup)))))


And last form returns "nil", so gnus-request-move-article also gets
"nil" even though the move is internal from one imap to another.

I get the same behaviour on Emacs-28 master and Emacs-27.
