[master] Compatibility with LHCbWebDIRAC for YAML based productions
Currently some production requests created with dirac-production-request-submit
can't be signed as there are errors like ProDetail can't be modified during PPG signing
and Extra can't be modified during PPG signing
.
This fixes the compatibility to behave more like the web app.
