Playernames of previous match persist in the next gamesetup

[elexis]

Sometimes we can see playernames of a previous match in the gamesetup.

This error cannot be fixed without deleting the persist-matchsettings or selecting a different maptype.

For years we didn't know how it could occur (so filing this report to have a ticket to find in case we need to look it up again).

But the reason is easy after accidentally finding it, doubleclicking on Start Game. The first call it will copy over the names, the second call it will save those to the persistmatchsettings file.

There is a different ticket for persist-match-settings saving less information. Playernames should be dropped as well eventually.
