Vertico and org-cite do not work well

[juanjosegarciaripoll]

Steps to reproduce:

1. Set up vertico-mode
2. Create an org-mode file with an initial #+bibliography key that points to some bibtex file
3. Attempt to insert a citation using C-c C-x @
4. Vertico will offer one option, but whenever C-j or RET is pressed, it simply adds one more key Wallquist2009: to the citation list, never finishing.
5. More generally, this seems to be caused by the fact that vertico-mode never allows for empty input on certain fields.

Example file example.org

#+bibliography: ./example.bib

Example bibliography example.bib

@article{Wallquist2009,
  title = {Hybrid Quantum Devices and Quantum Engineering},
  author = {Wallquist, M. and Hammerer, K. and Rabl, P. and Lukin, M. and Zoller, P.},
  year = {2009},
  month = dec,
  journal = {Physica Scripta},
  volume = {T137},
  pages = {014001},
  publisher = {{IOP Publishing}},
  issn = {1402-4896},
  doi = {10.1088/0031-8949/2009/T137/014001},
  langid = {english}
}

Try M-RET to submit the empty string. Please let me know if it works for you.

Why is this not offered as option in the C-h mode description?

I think it doesn't appear in the mode description since the vertico-map is only installed in the minibuffer. The command M-RET is also documented in the readme.

But org-cite could probably do a little better by passing the empty string as default argument. Then Vertico would directly accept RET to submit the empty string and the first candidate wouldn't get selected immediately.
