Modifies HasHttpStatus matcher for a more descriptive message

The message showed currently by the HasHttpStatus when de expected
status didn't match the actual status was not very informative, as
the actual status was not shown in the message.

This commit modifies this behaviour to show both status (expected and
actual) in the message.
