Motivated by #59 it looks like we need to replace prefer-expect-query-by* by better implementation to only force users to replace getBy queries by queryBy when:

• asserting elements are not present
• waiting for disappearance

This should be checked in several cases. A few I can think of at the moment:

• asserting with .not.toBeInTheDocument()
• asserting with .toBeNull()
• asserting with .toBe(null) this is actually an equivalent for the previous one, probably more variations to cover as .toBeFalsy() but I think just this one is enough for now?
• waiting for disappearance with waitForElementToBeRemoved

I can't think better name for this rule than no-get-by-for-element-absence, any suggestions?

*We could maintain prefer-expect-query-by when the new rule is implemented, but I think it wouldn't be that useful anymore and could even lead to confusion
