Fix intermittent metrics e2e test failure (#9980)
The metrics e2e test would fail if the segment events still weren't
dispatched when the page loaded. The Segment events are sent on a set
interval, so it isn't abnormal for them to lag behind the page load
itself. The `waitUntilCalled` utility has been used to wait until all
required events have been dispatched.

The `wait-until-called` module was converted to an ES5 module, so that
it could be used from an e2e test. The optional `callCount` parameter
has also been added, to allow waiting for more than one call.

The `segmentSpy` had to be converted to a `segmentStub`, to allow the
`waitUntilCalled` utility to be used.
