Fix tests for token flow having different error message

Depending on whether the test is executed in CA vs. running
them locally with `make test`, the resulting error message was
different for the `multiple-select-ui` and `ignore-provisioner-flag`
test cases. For now we just test for an error, but it would be
nice to refactor a bit and trigger specific error cases in the
future.
