Fix empty port stats when viewing rsvd ports only

This was a regression introduced in 1.3.0 as part of the port stats UX
improvement. The 'user' row was changed from the first (0) to the last,
but the proxy model continued to use a hard-coded value of 0 to check
for user to determine whether to show a port column or not.
