Problems due to account validation cache

[artob]

The __CREATE_ACCOUNT_VALIDATION_CACHE feature has been causing me trouble in trying to run the Balancer tests (near/nearcore#3665):

(That's with neard built from nearcore's evm-precompile branch, naturally.)

The trouble originates from these lines in src/utils.js:

https://github.com/near/near-web3-provider/blob/fc8f96491fd7aa35a186d5119e5659fe8cefe74f/src/utils.js#L340-L350

Logging the swallowed error in the aforementioned catch clause gives this:

TypedError: [-32000] Server error: account 1606505330670.test.near does not exist while viewing
    at JsonRpcProvider.sendJsonRpc (/home/arto/Sources/near-web3-provider.101/node_modules/near-api-js/lib/providers/json-rpc-provider.js:157:27)
    at processTicksAndRejections (internal/process/task_queues.js:93:5)

    at Account.fetchState (/home/arto/Sources/near-web3-provider.101/node_modules/near-api-js/lib/account.js:49:23)
    at _createTestAccount (/home/arto/Sources/near-web3-provider.101/src/utils.js:345:17) {
  type: 'UntypedError',
  context: undefined
}

For now, I've worked around the problem by simply commenting out the lines in question.

Have you encountered this issue, @mikedotexe?

You may want to try removing the files like this:

pwd=$(pwd)
echo "Attempting to remove old local accounts from $pwd/neardev/local"
rm -f $pwd/neardev/local/16*
echo "Attempting to remove old local accounts from ~/.near-credentials/local"
rm -f ~/.near-credentials/local/*.json

But that is not a good long term solution, just to get over this hump so we can both see the same tests failing/passing
