ui: Don't render tracks while the trace is loading

Since changing to the new workspace API, the tracks now get displayed
while the moment they are added and before they are grouped. This can
lead to the trace loads being slower as:
- Tracks's onCreate hooks are called as they momentarily appear on
  screen which can kick off expensive queries that we don't even see.
- We can end up with a lot of track DOM elements before grouping
  happens which can lead to slow DOM redraws.

This CL just hides all tracks until the trace has fully loaded (i.e. all
plugins have completed their onTraceLoad() hooks, which emulates the
prior behavior and speed up loading significantly.
