This change fixes tests on Chromecast by loading tests later in the process. Test scripts are now dynamically inserted by boot.js, rather than loaded by Karma. The bootstrapping code then awaits the completion of that before starting the Karma frameworks (Jasmine) to run the tests.
This also removes the use of goog.provide/goog.require in tests and test utils. We don't need to load test utils or library sources dynamically in each test, and this gives us more explicit control over script loading and ordering.
Closes#4094
According to the output documentation, |MultiMap.get| is supposed
to return null "if no such key exists".
However, in the case that an object is added to the map and then
removed, |MultiMap.get| will return an empty array instead of null.
This inconsistency could be relevant for code that tests based on
the truthiness of the output, so this CL changes the remove method
to delete the array for a given key if it becomes empty.
This also adds unit tests for MultiMap.
