[PR2 Bug] Guests receive wrong PM error message

[Master Raiden]

Problem: Guests who are Rank 3 or above receive the wrong PM error message
Type of Problem: Server
Expected Behavior: The correct reason for a failed PM is shown, or Guests are unable to access the Send PM button
Actual Behavior: Guests are always told that they need to be Rank 3 or above to send PMs

Steps to Reproduce the Problem:
1. Log in to PR2 as a Guest
2. Achieve Rank 3 or higher
3. Attempt to send a PM to someone
The PM will not be sent and you will be told that you need to be Rank 3 or higher to send a PM

Additional Information:
Before the Player Info popup was updated, the Send PM button was always disabled for Guests.
So I think the Send PM button should be removed for Guests, just like how the Share Level button is removed when viewing Level details.
