rippled/src/test/app/Escrow_test.cpp
Scott Schurr 3523cee63d Minimize use of jtx::with_only_features (RIPD-1515): 
In order to automatically run unit tests with newly created
amendments, prefer to start with jtx::supported_features() and
then subtract unwanted features.

These changes identified a few bugs that were hiding in
amendments.  One of those bugs, in FlowCross, is not yet fixed.
By uncommenting the test in CrossingLimits_test.cpp you can see
failures relating to that bug.  Since FlowCross is not yet
enabled on the network we can fix the bug at our convenience.
