Session filtering should ignore the route part of the session ID

[dnonglt]

There are two flavours of the session Id (such as 523F2857DD2B4536B7C86A479F0212E2 and 523F2857DD2B4536B7C86A479F0212E2-1:2) in the vizqlserver native API log, which means that when I use the TLV menu “Export to new tab > This session” (same for highlight), I miss lots of lines (only getting the matches for either of the two flavours but not both). I believe the session ID without the route part should be enough for identifying the session, and the two different formats should be treated as the same.
