[Bug Report] Creating new performers with same name unmatches other performers

[Darklyter]

Describe the bug
When in Tagger view, if you create a new performer that has the same name as other performers (ignoring disambiguation) then it will "unmatch" the other performers from their mappings between local Stash and StashDB/TPDB. Refreshing the page or rescraping the affected scenes will show the mapped performers correctly.

To Reproduce

1. Take an unmapped performer, for example "Trinity" and load scenes into Tagger.
2. Match scene 1 to "Trinity (2001-2007)" (create performer if necessary)
3. For scene 2, create a new performer named something like "Trinity (b1979, Hungary)" (creation will auto map performer)
4. When you save that new performer, scene 1 performer will now show as unmapped with the newly created "Trinity (b1979, Hungary)" as the recommendation.
5. Refresh page or rescrape scene 1, and "Trinity (2001-2007)" will again show as correctly mapped and matched.

Expected behavior
Would expect to not unlink other performers on new performer creation
