Add matchError overload which takes a predicate closure

[ikesyo]

That is similar to throwError one:

Nimble/Sources/Nimble/Matchers/ThrowError.swift

Line 237 in b35ec72

public func throwError<T: Error>(closure: @escaping ((T) -> Void)) -> Predicate<Any> {

Instead of adding NSError overload #615 (comment).
