Rails 6.1 breaks on "rake db:migrate" when parse-stack is included - TypeError: can't quote Parse::Operation

[hunterae]

I have setup a simple demonstration app to show this issue: https://github.com/hunterae/rails6-1_parse-stack-issue

Essentially, when using Rails 6.1.6 (also confirmed with 6.1.7), and parse-stack 1.9.1 (also confirmed with 1.8.0), and mysql2 0.5.6 (also confirmed with 0.5.4), whenever you attempt to run "rake db:migrate", you get an error that says "TypeError: can't quote Parse::Operation".

The full error stack looks like this:

The gem also prevents upgrading to Rails 7.

The issue seems to stem from the fact that the gem is dynamically defining "id" on Symbol. I added a fix by on my fork (https://github.com/hunterae/parse-stack) by hacking the method definition for Parse::Operation.register as follows (here's the commit: hunterae@a0cdc65):

module Parse
  class Operation
    def self.register(op, klass)
      Operation.operators[op.to_sym] = klass
      # Hack to get this working in Rails 6.1
      op = :object_id if op.to_sym == :id
      Symbol.send :define_method, op do |value = nil|
        operation = Operation.new self, op
        value.nil? ? operation : operation.constraint(value)
      end
    end
  end
end

I'm not making a PR for this commit as I imagine it breaks some of the existing functionality and I don't understand that portion of the functionality well enough to add a proper fix.
