Simplify karma.config.js by setting basePath

Set the base path for the karma test runner to h/static/scripts.

The only slight subtlety here is that client templates are now keyed by
their basename: loading them from above the base path results in the
paths being absolute when they get to ng-html2js-preprocessor, so
stripPrefix doesn't work.
