fix(thunk): run thunk supervisors immediately on register

For whatever reason, dispatching actions to register all the supervisor
thunks was too slow and causing a regression with prod systems.

This reverts part of the register function to how it used to work.  To
be more specific, it calls the supervisor functions immediately in a
`parallel` call.
