Another logging fix

Browse Source 
When renaming a log file, if the new name already exists we just
start appending to it and delete the old file. There's no need
to create a backup.

This fixes an issue where leaving and rejoining the same group
multiple times will eventually lead to the logger not working
due to trying to use the same file name over and over again.
