Fixed registration of the gateway test host

Gateways registered as separate modules (vub-eplatby, slsp) didn't have
the test host available. Originally (during loadConfiguration()) the
system wasn't aware of this additional gateways and they were registered
later.

Moving the registration to the beforeCompile() makes sure, that all
dependency (and gateway) definitions are available and system can
correctly register the test host.
