Commit: Adrián Medraño Calvo <adrian@medranocalvo.com>

    Refactor `exwm-workspace--get-remove-frame-next-workspace'
    
    * exwm-workspace.el (exwm-workspace--prompt-delete)
    (exwm-workspace--set-desktop): Stop explicitly moving X windows to
    other workspace; dealt with by
    `exwm-workspace--remove-frame-as-workspace'.
    (exwm-workspace--get-remove-frame-next-workspace): Remove
    function.  Refactored into `exwm-workspace--get-next-workspace'
    and `exwm-workspace--remove-frame-as-workspace'.
    (exwm-workspace--get-next-workspace): Add function.
    (exwm-workspace--remove-frame-as-workspace): Move X windows to
    next workspace.
