Tests failing due to changed tape behaviour

[marsell]

package.json uses tape 5.0.0 and above, but tape switched deep-equal library versions between 4.x and 5.x, and the new deep-equal has some strange behaviour: deepEqual() failing with objects that are semantically identical, but have a different ordering of attributes. For example:

    operator: deepEqual
    expected: |-
      { jse_info: {}, jse_shortmsg: '', message: 'Role(s) asdasdasdasd not found', statusCode: 409, restCode: 'InvalidArgument', name: 'InvalidArgumentError', body: { code: 'InvalidArgument', message: 'Role(s) asdasdasdasd not found' } }
    actual: |-
      { jse_shortmsg: '', jse_info: {}, message: 'Role(s) asdasdasdasd not found', statusCode: 409, body: { code: 'InvalidArgument', message: 'Role(s) asdasdasdasd not found' }, restCode: 'InvalidArgument', name: 'InvalidArgumentError' }
    at: <anonymous> (/opt/smartdc/cloudapi/test/auth.test.js:467:11)
    stack: |-
      InvalidArgumentError: Role(s) asdasdasdasd not found

          at IncomingMessage.done (/opt/smartdc/cloudapi/node_modules/restify/lib/clients/string_client.js:167:13)

          at IncomingMessage.emit (events.js:185:7)
          at endReadableNT (_stream_readable.js:978:12)

          at process._tickCallback (internal/process/next_tick.js:104:9)

I could fix the tests themselves, but since this new deepEqual() behaviour is nonsense, switch to using the older tape 4.13.2 instead.
