We added a conversion of failcodes that do not have sufficient information in
faac4b28ad. That means that a failcode that'd require additional information
in order to be a correct error to return in an onion is mapped to a generic
one since we can't backfill the information.
This tests that the mapping is performed correctly and replicates the
situation in #4070
