Subject: [PATCH] [BUGFIX] Prevent "undefined variable $isSavingOfMailAllowed
 in ... FormController"

One of our clients is using TYPO3 11 with powermail 10.8.1 (latest for this TYPO3 version so far). A form is set with activated double opt in. When the user clicks on the link in the mail to confirm the message, an exception is thrown.
