bugfix: load order issue in server, include test

Includes our first functional test. This one only makes sure loading
the bin/nickserver actually works fine. Enough to catch this bug.

+Integration tests for clients of remote services
+================================================
+
+The tests in this directory are integration test with remote services.  However
+we aims at testing the client side of the equation as that is what we control
+here.
+
+So unexpected server behavious should *crash* the test if we are not dealing
+with it properly yet and have no unit test for it.
+
+Server responses that we do not expect but handle in the code and test in unit
+tests make the test *skip*.
+
+The Behaviour we would normally expect should make the test *pass*
