Full test run fails

[jacque006]

What's wrong

When running the full test suite via npm run test, some tests will fail.

$ npm run test

...

  5) Integration Test
       Exit via mass migration:
     TypeError: Cannot read property 'tokenID' of undefined
      at StateTree._processMassMigrationCommit (ts/stateTree.ts:240:55)
      at _processMassMigrationCommit.next (<anonymous>)

      at Context.<anonymous> (test/integration.test.ts:290:23)

How can we fix it?

This is likely due to global state bleeding over between test(s)/suite(s). Will need to track down and update points in tests where this occurs and find a better testing pattern.

The same tests sometimes succeed when ran again.
