Errors in tests

There are a bunch of cases where we mock command.error using `command.error = jest.fn()`
The oclif behavior of command.error is to exit, however our mock simply swallows the error and continues. This means we have a whole bunch of places where we are testing for arguments and calls to functions that should never have happened because command.error should have exited.

Simply removing the mock in deploy.test.js reveals 38 errors, which are all invalid tests and need to be written.
