UserInitializer: info property of 'principalName' index not accurate

the description of the 'principalName' index definition stored in the 'info' property is IMHO misleading.
thomasm, do you recall what your intention was when stating if it was constructed manually? that sounds a bit odd as the rep:principalName property is always defined when a new user/group is created through the API. on JCR level users/groups cannot be created manually using regular write operations due to the protected nature some properties.
