Shared/Logs: Fix crash in Console log output

Browse Source 
Correctly handle the return value of vsnprintf() which returns -1 if the buffer is too small http://msdn.microsoft.com/en-us/library/1kt27hek.aspx . In this case just truncate the output.
This caused a crash on character delete if Logger.entities.player.dump was enabled and set to 3.
Fixes #11539
