Fixed fail for signer_newAccount in #58 and #57

[mersinvald]

Okay, most of the failures are due to test-coverage tool trying to pass randomly-generated params, which doesn't work well with stateful jade-signer.

PR #59 fixes that through skipping tests with no examples defined.

Current state:

Example Success:  signer_newAccount [
  {
    name: 'my test wallet',
    description: 'my test wallet description',
    passphrase: 'baz'
  },
  { chain: 'etc' }
