Raise an exception if a developer calls any of the GraphQL authorization
methods and a `authorize :permission` is missing from a mutation class.

Previously `authorized?` would return `true` in this situation, which
although technically is accurate is not what a developer is intending.

Squelch output of ActiveSupport::Cache::NullStore in tests

See merge request gitlab-org/gitlab-ce!30055

When a spec fails relating to the cache, the job log can easily exceed
the maximum length and make it harder to see the actual issue
(e.g. https://gitlab.com/gitlab-org/gitlab-ee/-/jobs/239803017).

Move vuex action helper spec to Jest

See merge request gitlab-org/gitlab-ce!29653

This is largely a straight-forward copy of the Karma spec, with the
usual Karma->Jest necessary changes.

This also fixes a bug in the implementation that was causing the tests
to fail, when run on Jest/node, whereby actions that return rejected
promises would always fail the given test. This was due to those
rejections not being caught in the same call stack in which they were
created.

Clarify that this.something is not available in Jest (docs)

Closes #24809
