FilesystemRealmEncryptedTestCase.SetupTask.tearDown tries to remove credential store INVALID_CREDENTIAL_STORE, but that store was never added. So the remove op fails and the exception means subsequent reload is bypassed. This can lead to subsequent failures, as described at https://github.com/wildfly/wildfly/pull/18569#pullrequestreview-2513595587

INVALID_CREDENTIAL_STORE looks to be cruft left behind in the WFLY-16190 work.
