Testing Tools - Provide a verbose message when the error should be thrown

[Dmitry-Ostashev]

Is your feature request related to a problem? Please describe.
I'm testing my aggregate using with the Testing Tools. If a command executed without an expected error, I can see the following message:

expected an error, but received no error received.

It's unclear what error should be thrown. Besides, the stack trace does not point to the particular line in my test file:

    expected an error, but received no error received

      at _callee$ (node_modules/@resolve-js/testing-tools/lib/flow/aggregate/make-test-environment.js:124:48)

Describe the solution you'd like
I want to see a message like in case if an incorrect error was thrown:

expected error "ForbiddenError: the user is not an organization owner or administrator. ", but received no error received.

Describe alternatives you've considered
Put each command call into a separate test.
