Better search job arguments (including integers) by adding serialized_params->>arguments explicitly

[bensheldon]

Fixes #1458

[swaathi]

Do you think test coverage can be improved to include this update?

good_job/spec/app/models/concerns/good_job/filterable_spec.rb

Lines 21 to 23 in b0c9707

	it 'searches serialized params' do
	expect(model_class.search_text('example_value')).to include(job)
	end

This tests only string arguments.

@swaathi yes, that would be the right thing to do 😉 I'll push a quick test for this.

Awesome! Thank you.
