UUID migrration fixes

Browse Source 
Firstly, remove incorrect unique index on playername (and UUID, just in case) columns, and add a non-unique index on the UUID column

Secondly, account for setups not logging onlinetime - in that case, try to look up ALL names, and give any not found the log_ prefix rather than the noimport_ prefix
