fix: Track state range is invalid if tip index is (#1995)
a7cd583 
This changes the track state ranges to return zero-length ranges in case the tip index is kInvalid. The VectorTrackContainer backend initializes the `tipIndex` to kInvalid, and so does the `addTrack`, so in principle this should always be consistent by default.

Fixes #1994
