Error when testing an observable with null emissions

[henry-alakazhang]

Hi,

If you try to test an observable that emits null, the test fails due to this error inside constructObservableMarble when it tries to pick a symbol:

TypeError: Cannot read property 'toString' of null
    at appendNotificationValue (http://localhost:9876/_karma_webpack_/webpack:/node_modules/rx-sandbox/dist/src/assert/constructObservableMarble.js:57:1)
    at Object.constructObservableMarble (http://localhost:9876/_karma_webpack_/webpack:/node_modules/rx-sandbox/dist/src/assert/constructObservableMarble.js:103:1)
    at Object.equal (http://localhost:9876/_karma_webpack_/webpack:/node_modules/rx-sandbox/dist/src/assert/marbleAssert.js:41:1)
    at ...

Version: 1.0.0

It looks like this is no longer occurs in master thanks to a095623, so a new release should fix this issue.
