Fix ActiveJob tests for Rails 7.2 and 8.0

[olivier-thatch]

Description

This PR fixes the test suite so that the ActiveJob related tests pass with Rails 7.2 and 8.0.

While working on the ActiveJob integration, I noticed that one of the tests was failing with Rails 7.2 and 8.0, specifically this one:

sentry-ruby/sentry-rails/spec/sentry/rails/activejob_spec.rb

Lines 310 to 324 in 1eb011b

	context "when we are using an adapter which has a specific integration" do
	before do
	Sentry.configuration.rails.skippable_job_adapters = ["ActiveJob::QueueAdapters::TestAdapter"]
	end
	after do
	Sentry.configuration.rails.skippable_job_adapters = []
	end
	it "does not trigger sentry and re-raises" do
	expect { FailedJob.perform_now }.to raise_error(FailedJob::TestError)
	expect(transport.events.size).to eq(0)
	end
	end

After investigating, I realized that with Rails >= 7.2, all the test jobs were using ActiveJob::QueueAdapters::AsyncAdapter as their queue adapter instead of ActiveJob::QueueAdapters::TestAdapter. This is likely because of this change that was introduced in Rails 7.2.

The fix is easy enough: we simply need to make sure ActiveJob::TestHelper is included before the test suite runs. After including the helper module, all test jobs correctly use ActiveJob::QueueAdapters::TestAdapter as their queue adapter.

What I don't understand is why this happens locally but not in CI 🤔

Thanks! Could you please rebase this on top of latest master before we merge it?

@solnic Done!

What I don't understand is why this happens locally but not in CI 🤔

@olivier-thatch on CI we run all the specs, and the spec fails locally only if you run it separately (at least for me). This means that there's some state that changes during whole spec suite run that causes this spec to pass, but it's different when we run it in isolation.

Thanks, this indeed fixes the problem :)
