Solve non-deterministic tests

[marcelomorgado]

Deal with already skipped test cases plus:

TasitAction.Contract > should emit error event when block reorganization occurs - tx confirmed twice (refs)

[marcelomorgado]

Some test cases still disabled (skipped) and some confirmations/blocks counts still as non-deterministic.
I think that all cases could be solved when these issues were addressed:

• Allow mining to be completely disabled on startup trufflesuite/ganache#248
• Add willPoll and didPoll events to provider.  ethers-io/ethers.js#393
• https://stackoverflow.com/a/50785284

@marcelomorgado Makes sense. Thanks for the update!

[marcelomorgado]

Recent failures to be addressed:

TasitAction.Contract > Transactions (Actions) Subscription > should be able to listen to an event before sending
Move from to.equal to to.be.at.least

TasitAction.Contract > Transactions (Actions) Subscription > should emit error event when block reorganization occurs - tx confirmed twice
Skip for now since no call was made to the listener.

Since PR #386 we haven't non-deterministic test cases anymore.
We can close this or wait for more test rounds before make sure that issues were solved.

Okay, great!! Thanks. I'll set a reminder to close this in two days if we don't run into any intermittent issues.

The test suite passed in this PR #389 , so that's good

@marcelomorgado This merge into develop didn't have the tests pass:

https://circleci.com/gh/tasitlabs/TasitSDK/655

tasit-action:   1) TasitAction.Contract
tasit-action:        Contract Events Subscription
tasit-action:          contract should call error listener after timeout:
tasit-action:      Error: Timeout of 8000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves. (/home/circleci/tasit-sdk/packages/tasit-action/src/contract/Contract.test.js)

[marcelomorgado]

I'll skip this test again for now.

I'll skip this test again for now.

Okay, thanks
