WIP maybe spotted a bug

There are two versions of code:

- commented out pieces
- active pieces

Commented out pieces use format of {id: doc._id, item: doc}.

Active code uses just doc and relies on _id.

When running with old code, tests fail and 'failedTests' template prints the
names of tests, those failed in test-in-browser mode.

When running with new code, tests fail and 'failedTests' template prints [object
Object] instead of actual strings. Inspection shows that the return value of
helper 'failedTests' actually returns an array of strings. Weird.

Show to Avital tomorrow...
