[UI] Teammate ultimate technique cooldown UI desync

Sorry for not having more examples to determine rate of reproduction or scope of characters affected or maps affected.

Had an instance (on Howling Abyss (Poro-king)) where we had interrupted our Caitlyn's ultimate with an early kill. This gave her a greatly reduced cool down as it should. However in discussing this over voice-chat it became apparent that MY (unsure about the rest of the team) UI indicator in the bottom right above the map showed her cool down as being on its normal cycle time aka the longer time. So...while Cait's ultimate became active again I was being shown it via the UI as remaining on cool down. We did go ahead and used Cait's ult (not being interrupted) before the desync vanished and it did successfully reset the desync as you would expect.
