Looks like filePrefix can be completely removed?

Do we now load all browser tests from the test server? In that case, we don't
have to hard code the port number any more which would be great (allowing us to
run the browser test scripts in parallel without getting into problems with
ports).

Now that the tests are loaded from the server, there is no need to hard-code the
port number in the test that uses it to load resources. Instead, we can use the
browser location object to construct the resource URI based on the current
location. The test we added the http server for was: 

date_time_format_http_request_test.dart

It uses the server to load a resource. Now that the test itself is loaded from
the server we don't need the port number in the test and can load the resource
relative to the current location?

This can be done as follow ups to this change.
