JobArtifact's 'zip' file_format collides with ActiveRecord::Relation's method
When running rails console
with rails 5.2, it fails to start with error message:
/home/honza/.rvm/gems/ruby-2.5.3/gems/activerecord-5.2.2/lib/active_record/enum.rb:235:in `raise_conflict_error': You tried to define an enum named "file_format" on the model "Ci::JobArtifact", but this will generate a class method "zip", which is already defined by ActiveRecord::Relation. (ArgumentError)
