skipUntil() operator behavior

[kwonoj]

Current implementation of skipUntil() does not handle some cases such as argument observable raises error like

var e1 =   hot('--a--b--c--d--e--|');
var skip = hot('-------------#');
var expected = '-------------#';

expectObservable(e1.skipUntil(skip)).toBe(expected);

Marble diagram of RxJS4 test expected to pass but fail.

I'll look into as well as expanding test coverage.
