Add recovery test using a code id that differs from that in the table of the defunct ledger

[achamayou]

A user recovering a ledger must be able to use new code.

I believe this is what the run_ledger_compatibility_since_first part of the LTS compatibility test already does.

@jumaffre good point, but I think it would still be good to have a generic, suite-able version (something that did a loggingcpp -> loggingjs recovery, or the other way around as the case may be). The LTS could re-use that with slightly different args?

[jumaffre]

@achamayou Yes, that would be even better!
