Non-critical Test Failures across both Mac and Debian systems

We've noted ongoing non-critical test failures on macs but now see some on @zig debian system which makes us wonder if some deeper system level difference causes the trouble.

From @margot 's mac we see

  565 passing (7s)
  3 failing

  1) routes
       "before all" hook:
     TypeError: Cannot read property 'server' of undefined
      at _callee$ (services/registrar/routes.spec.js:41:67)
      at tryCatch (/signalboost/node_modules/regenerator-runtime/runtime.js:62:40)

      at /signalboost/node_modules/babel-runtime/helpers/asyncToGenerator.js:28:13

  2) routes
       "after all" hook:
     TypeError: Cannot read property 'close' of undefined
      at Context.<anonymous> (services/registrar/routes.spec.js:42:22)

  3) dispatcher service
       handling an incoming message
         when the message is a expiry time update
           from a subscriber
             notifies the subscriber that their change was overriden:
     TypeError: Cannot read property 'args' of null
      at Context.<anonymous> (services/dispatcher/run.spec.js:543:18)

the last one in this list being unique...

On ziggy's system we see:

561 passing (6s)

in zig's errors #3 (closed) and #4 (closed) are duplicates of the previously noted "mac errors"
