Refactor karma config

- rename test:multi npm target to test-multi, for consistency with react-sdk
- base karma webpack config on the distribution one
- include Olm if we have it
- don't use the karma source loader - it's pointless given we webpack
  everything.
- turn off module listing in the webpack stats to shorten the console output
