* lisp/tab-bar.el (switch-to-buffer-other-tab): Normalize buffer.

* lisp/tab-bar.el (switch-to-buffer-other-tab): Use
'window-normalize-buffer-to-switch-to' on 'buffer-or-name',
like does 'pop-to-buffer' used by 'switch-to-buffer-other-frame',
instead of raising the error "Invalid buffer" on a non-existent buffer name.
