Then there was also Pre Vizsla mentioning how his ancestors stole his darksaber from the Jedi temple during the "fall of the Old Republic."
The bounty hunter who helps Malgus during the destruction of the Jedi Temple is called Visla (I know the "z" misses). But if I remember well, Bioware said she was Visla after
Vizsla story had been revealed in Clone Wars. So it's likely that it's not a TOR easter egg in Clone Wars but a Clone Wars easter egg in TOR
Or maybe Lucas Arts took inspiration in this trailer (it didn't have to be released yet because it must have Lucas Arts approval behorehand), created Vizsla, and only after BioWare named her accordingly. Crossed easter egg...
