Problems with the work of tags on cyrillic.

There are problems with the work of tags on cyrillic.
1. I created a note.
2. Tagged her "Инфо".
3. In the sidebar I have opened the edit tags.
4. I changed the label "Инфо" to "Информация" - the label has not changed.
5. I changed the label to "Info" - the label changed.
6. I go to the note - it is still with the old label "Инфо".
7. I delete the "Info" label - the old "Инфо" label remains in the note.
8. I delete the note - the "Инфо" label appears in the sidebar.
This does not happen with Latin marks.

Start by reproducing the numbered Cyrillic-tag flow in the Android app, then compare each rename and deletion step with the Latin-label case. Done means renamed Cyrillic tags update on the note and in the sidebar, deletion removes the tag everywhere, and no old label reappears after the note is deleted.
