Error on change the tab without changes on server config
When you open the tab "Mail" on "Server Config" and try to open another tab, even without change anything in the form, shows the error message "1. Uid-mapping cannot be changed if there are already mail users.".!
I noticed that the "mailbox_virtual_uidgid_maps" function (validate_server_mail_config class) looks up the server settings where ISPConfig is (when comparing the information between what is saved and the form), not the server selected in the server list.
