Two changes with regards to the 'eventwhencalled' option of queues.conf

1) Due to some signed vs. unsigned silliness, setting 'eventwhencalled' to 
   'vars' or 'yes' did exactly the same thing. Thus the sign change of the
   ast_true call.

2) The vars2manager function overwrote a \n for every channel variable it parsed, resulting
   in bizarre output for the channel variables. This patch remedies this.

(related to issue #11385, however I'm not sure if this will actually be enough to close it)
