By-channel metrics legend (on hover) missing `latest` track if it's not default

[Saviq]

Expected behaviour

The on-hover legend of metrics enumerates the major contributors to the total.

Steps to reproduce the problem

Go to https://snapcraft.io/ubuntu-frame/metrics?active-devices=channel and hover on the graph to see the legend.

I've raised this with the store team as it seems like the store API is indeed not returning the latest channel if it's not default.
