Removing the jenkins:credentials:type tag from a secret does not make it disappear from Jenkins

[chriskilding]

If the type tag is removed, then the credential should disappear from Jenkins when the cache is reloaded.

But what happens at the moment is...

Given I have a Secret Text credential stored in Secrets Manager (with the jenkins:credentials:type=string tag)
When I remove the type tag, and wait for the credentials cache to reload,
Then the Secret Text credential still remains in Jenkins.

(It only disappears after I initiate a delete to remove the secret altogether, regardless of whether that tag was present or later removed.)

Moved from JENKINS-61112
