This reverts commit 73f448e5.

The specs that rely on a correct value of the trackable attributes, should
include the `:redis` keyword in the spec to ensure the state is reset between
various specs.

The trackable attributes being:

- sign_in_count      : Increased every time a sign in is made (by form, openid, oauth)
- current_sign_in_at : A timestamp updated when the user signs in
- last_sign_in_at    : Holds the timestamp of the previous sign in
- current_sign_in_ip : The remote ip updated when the user sign in
- last_sign_in_ip    : Holds the remote ip of the previous sign in

The limiting of writing trackable attributes was introduced in
gitlab-org/gitlab-ce!11053.

Fix OpenID spec failure that assumed current_sign_in_at would be set

Closes #32041

See merge request !11219

Due to 6a915d6f, the `current_sign_in_at` may not actually be set due
to an ExclusiveLease in other jobs. To fix this spec, manually set
the value in the setup.

In commit 020295ff a regex was added to quickly determine if mentionables might
be referenced. But this didn't take into account the note might not belong to a
project. So when it doesn't belong to a project, assume the default issue
tracker is used, and use DEFAULT_PATTERN to check if there are mentionables.
