Fix restart issue with deal transferring

[aarshkshah1992]

Closes #378 .

[aarshkshah1992]

@hannahhoward Let me know if we need to test the restarts after more events.

[hannahhoward]

@aarshkshah1992 I would check ClientEventDealPublished and ClientEventDealActivated as well, though you can do so in a seperate ticket. That will also probably require making sure the node methods to not return immediately, as I imagine the final states are moved through in quick sucession during test (in a real environment, it's not quick)

[hannahhoward]

Please run make prepare-pr before merging to pass the docs-check

@aarshkshah1992 also TestMakeDealNonBlocking being flaky is a known issue -- if you want to look at that in a seperate ticket you're welcome to.
