    project-switch-project: Use a different fix for bug#58784
    
    * lisp/progmodes/project.el (project-current-inhibit-prompt):
    Rename to 'project-current-directory-override', and make it a
    string value.
    (project-current): Refer to it.
    (project-switch-project): Bind it.  Drop the temp buffer (bug#58784).
