commit 7f14b23914e43c3062facfd82f4430be218a9b2a
Author: MS <ms@taler.net>

    Nexus testing.
    
    Up to the point where Nexus gets launched and
    the Exchange user & bank connection get created.
    
    The test fails because the bank connection of
    type "loopback" is not implemented in the nexus
    yet.
