Run unit tests in Chrome instead of PhantomJS

This commit adds karma-chrome-launcher and changes karma's settings
to use Chrome for all unit tests, removing PhantomJS. This change
is mainly to avoid downloading PhantomJS during gate tests, as the
phantomjs platform binaries would be downloaded from bitbucket and
their download servers have been returning rate limiting jobs and
returning 429 errors, leading to failed test runs. Since Chrome is
automatically installled from local mirrors, this should avoid the
problem entirely.
