Subject: [PATCH] chore(build): fix karma not exiting properly (#1741)

* Fixes the Karma tasks not exiting properly. This is an issue, because doing a keyboard interrupt doesn't stop the Gulp watchers that are going on in the background.
* Increase the time that Karma waits before starting to run tests. This should help mitigate the multiple reloads when running unit tests locally.

Related to #1681.
