Prevent garbage from being saved in the userid field

Browse source 
It seems that in some scenarios we end up with a string that isn't NUL
terminated and that results in garbage being stored as userid. This patch
is a little brute force but it fixes the problem even if a previous
version os Subsurface ended up adding other text to the end of the userid.
