If olm is not installed, the webpack build for the karma tests gives an ugly
error. None of the tests currently care if olm is installed or not, so fix this
for now by just ignoring the olm module.
* Make sure we only get one js-sdk (and update runtime config to match)
* Don't verifyNoOutstandingRequests (since it is hard to be certain which we
will get, and makes the tests too dependent on implementation-specifics).
* Disable color for npm test, to avoid confusing Jenkins
