Many commands had insufficient failure testing. This adds new tests that ensure that for every Process call, at least one test fails if a failure from that process were ignored (with the exception of calls in the `publish` command, which has a custom process mocking system, so was out of scope here; it already has more coverage than most tests did though.) For a few existing failure tests, adds output checks to ensure that they are testing for the *right* failures. Other changes: - Adds convenience constructors to MockProcess for the common cases of a mock process that just exits with a 0 or 1 status, to reduce test verbosity. - Fixes a few bugs that were found by the new tests. - Minor test cleanup, especially cases where a mock process was being set up just to make all calls succeed, which is the default as of recent changes.
