Reviewed by Chris Dumez.

`MediaSource::ensureWeakOnHTMLMediaElementContext` took a strong ref to the 
HTMLMediaElement but this code can be called while the HTMLMediaElement is 
being destructed.

`ASSERT(!deletionHasBegun());`

We use a RefPtrAllowingPartiallyDestroyed instead which avoid the problem for 
now.

Ideally the logic should be refactored to avoid calling the method in the first 
place
if the HTMLMediaElement has gone away.
