Trying to get the test to untick the right Unreleaved checkbox and then check that the work is revealed. Not quite there.
Merge branch 'master' into Issue-2241-Individual-reveal-test
Worked out which Unrevealed checkbox to uncheck to get the right work to pass the test; added deferred message for Issue 2243 which prevents the revealed work from triggering an email.
Sync Gemfile.lock with current master copy.
Merge pull request #1546 from ariana-paris/Issue-2241-Individual-reveal-test

Issue 2241 and 2243 - reinstate individual reveal test and disable only the broken step
