System tests are not going to work until protocol 21 support is included in quickstart.

@dmkozh I enabled protocol 20 integration testing and the simulation library fails with:

cannot create budget from network configuration
        	            	
        	            	Caused by:
        	            	    HostError: Error(Budget, InternalError)
        	            	    DebugInfo not available

I double-checked that we are passing down the right protocol number (20).

All protocol 21 tests are passing without problems.

@sreuland I presume system tests are still using version 20 of the protocol, which would explain why they are failing.
