#1900 Project Viewer inconsistency

[Edward Diener]

In PV when I have the "Follow active buffer in tree" option checked, PV does indeed show the active buffer in the PV tree. Yet when I add the active buffer to PV, through the PV "Add current buffer" action, PV does not show the added active buffer in the PV tree. I have to switch to some other buffer and then back to the recently added buffer for PV to show that recently added buffer in the PV tree.

It would be nice if this could be fixed so that PV immediately shows an added current buffer in the PV tree.
