Error in test of bypros

[ineiti]

The following test in bypros has a Heisenbug and fails from time to time: TestProxyCatchUp_Multiple_Blocks

One example failure on my machine is:

W : api.go:743 (byzcoin.(*Client).WaitPropagation)         - error while querying node local://127.0.0.1:2020 - ignoring
    bctest.go:179: 
        	Error Trace:	bctest.go:179
        	            				bctest.go:152
        	            				proxy_test.go:290
        	Error:      	Received unexpected error:
        	            	didn't get the same blocks from everybody within 10 seconds:
        	            	    go.dedis.ch/cothority/v3/byzcoin.(*Client).WaitPropagation
        	            	        /Users/ligasser/Programming/DEDIS/cothority/byzcoin/api.go:779
        	Test:       	TestProxyCatchUp_Multiple_Blocks

But also github actions joke from time to time...

@nkcr - this is of course very low priority...
