* fix exception when manually querying for unsynced guild/arena-team
that shares it's name with another guild/team (e.g. ìíîi is the same to SQL)
and the target guild/team not being the first result
* TCs guild and arena_team tables as encoded as utf8mb4_general_ci,
which is not accent-aware. So we have to get all results and filter
for the correct one in php.
* fixes an issue where direcly accessing a guild/arena-team whith a name
simiar to an already known guild/team would lookup the wrong subject
on the server and then fail to create a local stub with already existing key.
