test: rename CT to harnessTest, ensure all RPC's get distinct timeouts
This commit slightly modifies the existing CT struct in order to maintain consistency with code-style. As a result of the name change, all references have also been renamed from `ct` to `t`. The Error and Errorf methods have been removed in favor of forcing everything to be reported via `Fatalf`. Additionally a new method (ProcessErrors) has been introduced to the networkHarness class in order to encapsulate the underlying channel.
