bug#56741: 29.0.50; M-X fails, if run from the active minibuffer

[Max Brieiev]

1. emacs -Q
2. Run any command that uses minibuffer, where candidate match is
   required, for example, 'C-h v'.
3. Run M-X and notice it fails with error:

    execute-extended-command-cycle: No catch for tag: cycle, ("" . 0)
