Call ignore_model_if before RbsRails::ActiveRecord.generatable?

[kyanagi]

RbsRails::ActiveRecord.generatable? may raise an exception.
For example, this occurred when using ActiveType::Object.

require "bundler/inline"

gemfile(true) do
  source "https://rubygems.org"
  git_source(:github) { |repo| "https://github.com/#{repo}.git" }

  gem "activerecord"
  gem "sqlite3"
  gem "rbs_rails"
  gem "active_type"
end

ActiveRecord::Base.establish_connection(adapter: "sqlite3", database: ":memory:")

class X < ActiveType::Object
end

p RbsRails::ActiveRecord.generatable?(X)

If we call ignore_model_if before generatable?, we can handle such cases by adding models that cause errors to ignore_model_if.
