Description

There are several places to check if a group is the "default" group, where the input could be a String or a RSGroupInfo.
It is better to provide official functions in RSGroupInfo to tell if a group is the default group, so as to

• Simply the code
• Make it more safe. It is not safe as there is no null check like

  if (!group.getName().equals(RSGroupInfo.DEFAULT_GROUP))
  

  It is more safe to check like:

  RSGroupInfo.DEFAULT_GROUP.equals(group.getName())
