@chemoish when the src redefines the current source, with a single so…

…urce, have the current sources be set to null.

When the `currentSources()` are called after `src('http://example.com')`, expect the `currentSources()` to only return the newly set source.
This way sources, via `<source>` or `src([...])` list, should never be out of sync when redefining a single source.

Updating tests to specify behavior changes. Remove autoplay from fixtures to bypass `loadTech()` ramifications.
