Introduce a feature to avoid "Invalid Ethereum transaction nonce" in the OZ tests

[vasiliy-zaznobin]

It needs to add a feature:
A test should use the right nonce for a transaction by sending getTransactionCount.

For example: test/utils/escrow/RefundEscrow.test.js

  2) Contract: RefundEscrow
       once deployed
         closed state
           "before each" hook for "rejects deposits":

During investigation it was found that this issue is caused by parallel execution of eth_sendRawTransaction with the same nonces. The behaviour is next:

1. beforeEach hook maps async lambda on array with eth accounts (line 63 in RefundEscrow.test.js)
2. lambdas simultaneously calls RefundEscrow.deposit() contract method using the same nonce - this is approved by proxy's logs.
3. evm loader fails transaction that was received later.

After talk with @otselnik we concluded that this behaviour is expected. The solution to this issue could be forcing tests to execute functions in sequential manner - this approach was tested by me on local environment with this particular test case and approved to solve issue
