Subject: gitk: Fix bug causing undefined variable error when cherry-picking

When "Show nearby tags" is turned off and the user did a cherry-pick,
we were trying to access variables relating to the descendent/ancestor
tag & head computations in addnewchild though they hadn't been set.
This makes sure we don't do that.  Reported by Johannes Sixt.
