Handle the case of missing certificates.

Creating a data channel or negotiating it can make the SCTP transport
name go from nothing (empty string) to something. Inside the
RTCStatsCollector this is relevant because which transports we have
affect which certificates we should cache, so this is an instance of
having to call ClearStatsCache().

The bug is that we don't. This CL fixes the bug.

I tried to create unittests to cover this, but I was unable to
reproduce the race in a testing environment (if I did it would have
hit an RTC_DCHECK). Not ideal... but I hope we can land it anyway since
the fix is trivial and clearing the cache in response to API calls is
worst case harmless.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development
