(*bucketDataSource).handleRecv panic: runtime error: slice bounds out of range

I'm seeing this during some test development, where I think one test might be leaving a DCP connection open, and the next test is flushing the bucket and then opening a new DCP connection.

Couchbase server: 4.1.0-5005 Community Edition (build-5005) 

If needed, I can provide detailed steps to repro.

Here's the panic message:
