Tests hang when expectations aren't met

[OfirD1]

Seems like a bug in all tests that eventually executes query in their call chain: When some expect evaluates to false, the test hangs.

The reason is that on one hand, these test functions get a done argument, while on the other hand, these test functions eventually have an (IIFE) async call (inside query).

Since an exception is thrown when some expect evaluates to false, done is never called in these test functions.

• Note the difference between these test functions and (for example) functions that internally call post, which is not async.

I think the solution is to add try-catch to all tests, and make sure done is called.
