[Rseding] [0.18.9] Refineries do not support backer names despite prototype

[GotLag]

Oil refineries don't show backer names, and supports_backer_name() returns false when run against them in-game. However, the prototype for oil-refinery shows has_backer_name set to true

As per the prototype documentation, has_backer_name is a supported property of type assembling-machine, so either that's not true any more or the prototype loader is skipping that property when it shouldn't be.

[Klonan]

Backer name was removed from crafting machines back in 2017, however the prototype fields were not removed properly.

Thanks for the report. It's now fixed for the next release.
