This commit mocks the website service for all the QUnit tests.
As the website module now defines a patch on the WebClient and NavBar
components, adding the website service, this service needs to be mocked
for all the tests. This is done by patching the QUnit.testStart hook.
Also, after the addition of the new media dialog, this component is
mocked at the field html unit test.
See merge commit for more information.
