Fix UnhandledPromiseRejectionWarning - closes #582

[yatki]

What was the problem?

2 tests were throwing UnhandledPromiseRejectionWarning

How did I fix it?

We decided to combine two tests into one, since one of them was returning PromiseRejection anyway.

Review checklist

A more direct solution would return queryResult.catch(() => {}) from the beforeEach hook. That way we wouldn't have to change our test code.

yea, that might have been easier, but we thought those two separate tests were more like the same case running twice

@shuse2 I'm ok with it
