ui: Use UUIDs for table names in all tracks

Currently there is a potential race when using the trackKey to
generate table names. When a track is desroyed, it is destroyed
asynchronously, so it can take a little while before e.g. tables are
dropped. This means that tracks can be destroyed and recreated with the
same trackKey before a previous incarnation of the track has been
destroyed resulting in table name clashes.

While there might be better ways to address this issue at a global
level, this patch implements the easy solution - using a uniquely
generated uuid per track instance to create table names instead of the
trackKey.

This could inroduce memory spikes, while new tracks are initialized
while old tracks still exist, but it's better to be functionally
correct at least for the time being, and this is no worse than it was
before.

This patch also addresses a formatting issues in base_slice_track.ts
where the unsanitized track key was being used in the table name
which could contain underscores e.g. in debug tracks.
