HttpClientTests: Use assertEquals to assert about response code

The current usage of assertThat causes a warning in Eclipse:

  "The expression of type int is boxed into Integer".

Replace it with assertEquals which does not cause this warning, and is
consistent with how such assertions are done in other tests.
