Fixes unexpected exception message in ProjectUserQuotaNotFound

When an exception ProjectUserQuotaNotFound occurs, the message "Quota
could not be found" was obtained. This is because the name of the
variable to override is incorrect. There is a similar bug in
ConsoleTypeUnavailable and ISERTargetNotFoundForVolume.
