Breaking change for rejectedWith

[cloverb]

Node.js 10.14.0
Should.js version 13.2.3

Repro here: https://repl.it/@cloverb/WeirdWeepySpheres

AssertionError: expected [Promise] to be rejected: expected CustomError {} to match CustomError {}

rejectedWith no longer works with custom errors because it calls match which then does an isPlainObject call which checks the object prototype. This is a breaking change from earlier versions. Is there a reason you are requiring the prototype to be Object.prototype or null?

Your code does not throw for me

Did you run it in the repl.it?

Is this still actual?
