While reviewing the file test_pkcs11_management.js added in bug 1357391 for inspiration for my own PKCS#11 management add-on, I noticed that I forgot one "await" in the test suite. The result is that there will be an assertTrue() on a Promise (which will always be successful) rather than on its resolved result.
This shouldn't cause the test suite to succeed when it shouldn't, because if the module isn't successfully loaded then the next batch of tests that try to use it will fail, but it's confusing and not proper.
If you'd like to set up a profile on mozillians.org, I'd be happy to vouch for you.
Added "qe-verify-" flag (test-only change).
