Jordan Rose cea47b78fc [analyzer] Fix trackNullOrUndef when tracking args that have nil receivers. 
There were actually two bugs here:
- if we decided to look for an interesting lvalue or call expression, we
  wouldn't go find its node if we also knew we were at a (different) call.
- if we looked through one message send with a  nil receiver, we thought we
  were still looking at an argument to the original call.

Put together, this kept us from being able to track the right values, which
means sub-par diagnostics and worse false-positive suppression.

Noticed by inspection.
