These changes originally from #6652, but pulled out to be merged separately. `outputBuffer` is a simpler way of asserting tests against the CLI output instead of working directly withe Jest mock function. `output.isTTY` is also now mutable, so that we can write tests for both cases when the output is different based on TTY-ness (for example, see the updated `vc whoami` tests in this PR).
