Noticed a minor (and very unimportant) glitch as a result of JENKINS-51447.

After previously failing to download 2.123, and then manually triggering an update check, the error popup now reads "Upgrade to Jenkins 2.124 failed: Failed to download from http://updates.jenkins-ci.org/download/war/2.123/jenkins.war (redirected to: http://mirrors.jenkins-ci.org/war/2.123/jenkins.war)." (Note the version mismatch between the message and the URL - they matched before the 2.124 update was detected).

Triggering the retry correctly downloads the newly released 2.124.

(The above was starting from an existing 2.122 installation).
