Fix alert management fingerprints
What does this MR do?
ActionController::Parameters
class is prefixed with #
in Rails 6.1. It changes the expected fingerprint.
The test because the specified fingerprint is no longer valid: https://gitlab.com/gitlab-org/gitlab/-/jobs/1207375993
Let's rely on the .to_json
output instead of .to_s
. Its format is unlikely to change
