Add a test case for #388

[ikesyo]

Ref: #388

[ikesyo]

We should test this here instead:

Nimble/Tests/NimbleTests/Matchers/AllPassTest.swift

Lines 79 to 86 in 8aa77bc

	func testAllPassCollectionsWithOptionalsDontWork() {
	failsWithErrorMessage("expected to all be nil, but failed first at element <nil> in <[nil, nil, nil]>") {
	expect([nil, nil, nil] as [Int?]).to(allPass(beNil()))
	}
	failsWithErrorMessage("expected to all pass a condition, but failed first at element <nil> in <[nil, nil, nil]>") {
	expect([nil, nil, nil] as [Int?]).to(allPass({$0 == nil}))
	}
	}
