Don't disable GC, let's fix any bugs that caused us to disable the GC.

Fixes #598
Remove importing of conditions from the product/conditions directory.

It's not currently in use since all the yaml files are disabled.

YAMLImportExportMixin is responsible for importing conditions and only calls
Condition#export_to_array or Condition#import_from_hash.

All of the other stuff is unused.
sync_from_file is now unused.
These were only used by the now deleted product/conditions yamls.
