The "problem" is that in 29, there's a new command emacs-news-view-mode
which also happens to be a possible match for input "em-v" when
partial-completion is in completion-styles (which it is by default).
That emacs-version is matched by "em-v" is also due to the
partial-completion style, so removing that won't do either.

If you really need emacs-version so frequently that you need a
super-short and unambiguous name for it, define an alias:

  (defalias 'ev #'emacs-version)

Then you can do M-x ev RET.
