ilo_deploy driver has poor test coverage for continue_deploy

[aeva black]

There is only one test handling an error path for the _continue_deploy method, and it merely asserts that an invalid initial state results in a LOG message being written out.

It would be better to assert that, when given a valid initial condition, any exceptions raised by methods called from _continue_deploy are handled appropriately.
