BUGFIX: Trim leading and tailing whitespaces

[markusguenther]

Whitespaces like a tab can lead to a 404 error if a URL has been pasted to a LinkEditor or LinkInput.

As data sources, assets, URLs and slugs should not start with a whitespace, we can remove them.

Fixes: #3859

If I missed something, please let me know. Also thought about an editor option to trim that, but that would be more a feature than a bug fix then.

The acceptance tests will run when #3855 has been merged. At the moment they are broken.

Looks good to me by reading, thx!

Thanks for having a look!
I tried it out, but it only works when entering something by hand. Copy/pasting a URL with tab/space still saves with the space.

Will test it again, but also used the Clipboard.

@pKallert Don't know why it worked before for me 🙈. Thanks for the test and review.

Ok , as the handleSearchTermChange is called on each keystroke we trim also spaces while entering text, so I now just trim the beginning at this point and when the Link should be applied manually we know that nothing should change anymore, so I can also trim the tailing whitespaces.

Hope that we now have a solution that works for all cases 🙈

Finally, tests are also passing 🥳

Works like a charm, thank you!
