Subject: [PATCH] New unit-test ServerTest.CacheIdsOfStaticResources

Introduced a new unit-test which will ensure that static resources of
kiwix-serve have the cache ids applied to them in the links embedded into
the HTML code.

At this point there are no cache ids. The new unit-test will help to
visualize how they come into existence.
