Improve logging of dangerous userdata edge cases (#3969)

Browse Source 
This commit improves the logging of a few edge cases that can lead to loss of userdata:
- Third-party plugins forcing creation of a NPC account which could not be found on the usermap, even if the account file exists
- UserMap#trackUUID being called with a conflicting UUID but replace set to false
