failCommentCondition isnt checked for "success" step

[rhys-childs]

failComment is marked as deprecated, but failCommentCondition isn't actually checked in the success step like failComment was.

failCommentCondition was added to the config here

The deprecation warning was added to the fail step for failComment here

But the same check is not performed here

The result is that you have to use the deprecated failComment config value to disable issue checking on the success step.
