Better version of parsing rawName to user titles and names

 - add new version of method parseCommonName
 - parse titleBefore, firstName, lastName and titleAfter
 - do not use 1 regex like in the last version of method, instead of it
   parse all values to the array by spaces and then choose which value
   is which part of user full name
 - add UtilsIntegrationTest with test of method parseCommonName
 - fix catching InternalErrorException in registrar on calling method
   parseCommonName (there is no InternalErrorException now)
