Avoid useless search with minCharacter

[pierre-H]

I noticed with the Admin Order Creation Plugin that event when there is no character, a search is done.

The base of this pull-request was changed, you need fetch and reset your local branch
if you want to add new commits to this pull request. Reset before you pull, else commits
may become messed-up.

Unless you added new commits (to this branch) locally that you did not push yet,
execute git fetch origin && git reset "patch-2" to update your local branch.

Feel free to ask for assistance when you get stuck 👍

Hello Pierre, could you take a look at the failing build and see what's causing it? Thanks! :)

[pierre-H]

@Zales0123 I don't understand why the build is failing … That's strange ...

[Zales0123]

Do these scenarios work on your machine?

[pierre-H]

I didn't try on my machine : I used the GitHub online editor.

The build is failing because the test client does not fill in the field so there are no characters.
Anyway, I think we fixed it with #10404, limiting default results to 25 makes the search much more performant and also allows for selecting a choice without filling the input (which might be helpful eg. if you have not that much taxons in your app).

Thanks for the PR and sorry for such a delay.
