Flush queued frames when processing coalesced packets

This fix mimics the code in QuicConnection:: MaybeProcessUndecryptablePackets, thanks rch@ and fayang@ for the analysis!

This issue was found by Chromium Clusterfuzz:
https://bugs.chromium.org/p/chromium/issues/detail?id=992831
I've confirmed that clusterfuzz test case 5646143163072512 no longer reproduces with the fix.

The new test fails without the fix and passes with it. More generally, increased test coverage for this area of code is tracked by b/139422067.
