Fixes an error when matrix-js-sdk is symlinked into node_modules, which meant
that we would (try to) use the version of olm from js-sdk instead of
vector-web (https://github.com/vector-im/vector-web/issues/1765).
Since https://github.com/matrix-org/matrix-js-sdk/pull/141, the jenkins build
does pull in the olm module, but because it's using npm v2, buries it deep in
node_modules. Rather than using the `fs` module to hunt for it, just try to
`require` it in the webpack config.
* 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
Hopefully, this fixes https://github.com/vector-im/vector-web/issues/1046
without any side-effects.
It relies on the fact that the languages files are pretty simple - in
particular, they don't require any other modules. So we can tell webpack just
to suck them in as they are, rather than parsing them and causing an explosm.
Webapck actually supports loading input source maps and generally seems a lot
more solid then browserify (even if their website has an annoying animated
logo).
