Frequent "user-agent-http-client.js POST http://localhost:9090/v1/sessions/start 500 (Internal Server Error)" when rapidly opening new tabs #1321

@victorporof do you see any logging around this? This is a helpful spur to get the UAS logging boned up.

A little logging later, I see

caught error { Error: SQLITE_ERROR: cannot start a transaction within a transaction
    at Error (native) errno: 1, code: 'SQLITE_ERROR' }
POST /v1/sessions/start 500 20.640 ms - 106

I thought we would block transactions at this point, but that's not so -- we need to process them sequentially. I'll figure out what the JS version of the talking stick is.

Should be fixed by https://github.com/mozilla/tofino/commit/c905c10883c0724bd5e55bd81bfdbec46a2c5536. Don't know why this didn't autoclose; guess my commit message syntax wasn't correct?
