Simulating phrase messages is problematic

[brunchboy]

Describe the bug
The context in which phrase expressions are simulated is missing actual phrase context in the runtime information, which tends to lead to NullPointerExceptions.

To Reproduce
Set up a phrase cue with a beat expression like:

(timbre/info "phrase beat ran, phrase-type:" phrase-type)
(when midi-output
  (midi/midi-note-on midi-output 0x10 (phrase-velocities phrase-type) (dec device-number)))

When you try to simulate it, you will find that phrase-type is nil, which crashes midi-note-on.

Options
It seems we can either send in a modified version of the show where there seems to be a track with phrase analysis playing, or at least enough of such for the basic phrase convenience variables to work. If that is too hard, remove the simulation options for phrase cues.

A potential avenue to address this would be to add the song structure tag to either or both of the sample tracks already embedded in the Jar for simulated OBS overlays when offline. Then the phrase structure simulation functions could create status objects that correlated with phrases from within those sample tracks.
