@change, and other @ tags, needlessly carried over to merged sentences

[morbrorper]

If a sentence that has a @change tag is changed, and the change results in a merge with another sentence, the tag is copied to the remaining sentence. This leads to a confusing state that can only be corrected by the owner of the tag, if they happen to notice, or an admin.

Of course, this applies to all @ tags, such as @needs_native_check.

Suggested solution: Make Horus exclude tags prefixed with "@" in copying tags when merging sentences.

I've deliberately labelled this a bug, even though Horus is just doing its job, as I consider it a bug in how Tatoeba works.

Yes, related, but not identical, as this only concerns special tags, prefixed with "@".
