fix(test-tooling): use of hardcoded password

Primary Changes
----------------
1. Updated line 236 in openethereum-test-ledger.ts so the default password argument to the
newEthPersonalAccount function is not hardcoded.

Fixes hyperledger#2766

BREAKING CHANGE: A line exceeding 100 characters has been split into two lines.
