Query string tokenizer could return a list containing empty tokens when the query string was `\` or `"` (probably in other scenarios as well).

This seems undesirable and is what triggered #8260, but I'm posting this separately from that fix in case I'm wrong. Feel free to reject if so.

The actual change in behavior is that now searching for `\` or `"` behaves the same as if the query were empty (the bleve/elastic code checks that the tokenizer actually returned, anything rather than just query being non-empty).

### Tests

- I added test coverage for Go changes...
  - [x] in their respective `*_test.go` for unit tests.

### Documentation

- [ ] I created a pull request [to the documentation](https://codeberg.org/forgejo/docs) to explain to Forgejo users how to use this change.
- [x] I did not document these changes and I do not expect someone else to do it.

### Release notes

- [x] I do not want this change to show in the release notes.
- [ ] I want the title to show in the release notes with a link to this pull request.
- [ ] I want the content of the `release-notes/<pull request number>.md` to be be used for the release notes instead of the title.
