on_load does not execute anymore

[jdpigeon]

I've ran into an issue after updating to the new npm version of jspsych-react. The lifecycle callback method on_load, specifically does not seem to be firing anymore.

Have we switched to an outdated version of jspsych that doesn't have on_load anymore?

The issue appears sometime after 0a81974 and is not due to changes in the timeline or plugins passed to the Experiment component.
