Migrate To A Newer Version

We migrate our code to work on https://github.com/Agoric/agoric-sdk/commit/fedf049435d7307311219fbab1b2b342ec6acce8 this commit

Note to other dapp devs @nunolleite @JorgeLopes-BytePitch

The biggest problem I faced during the migration is to migrate ava from version 3 to version 4. The error I got is something like below;

 Uncaught exception in test/test-stopLoss.js

  AssertionError [ERR_ASSERTION] [ERR_ASSERTION]: The expression evaluated to a falsy value:

    assert(refs.runnerChain)


SES_UNHANDLED_REJECTION: (AssertionError#1)
  ✖ test/test-stopLoss.js exited with a non-zero exit code: 1
  ✖ Couldn’t find any matching tests

And this problem has a closed issue here. Agoric engineering team also faced this issue when they were upgrading ava from v3 to v4 and had an internal issue about it here where they discuss this problem in the context of agoric-sdk. To solve the problem I've followed the steps in this pr where they upgrade dapp-card-store ava version from v3 to v4.

Conclusion

It's a useful thing to keep in mind when we try to migrate dapps from older versions to newer versions.
