Remaining Time on True Sight doesn't change on using potion

[feeltheburn]

Situation: You already have True Sight. If you click a TS potion while you already have TS, it doesn't reset the blue countdown graphic in the lower left corner. The blue will continue counting down the previous TS time limit, and then the TS image will just remain there with no timer until the potion's TS wears off.

If you use the TS magic spell, this doesn't happen.

To test: Use a TS potion. Wait until you can visibly see the blue timer behind the image has dropped enough, and use another TS potion before the previous TS expires.

This looks like its because the server does not sent the duration message if a potion is used while the buff is active. It does send the duration message for cast spells, even if already active. Perhaps @raduprv can take a look.
