Fix weird wrapping with multiple tab stops (^I)

[ParabonDabe]

Problem

Per https://github.com/f/atom-term2/issues/34

Solution

term.js::resize() was calling setupStops() before updating this.cols, but setupStops() uses the value of this.cols to know how many tabStops to create:

--- a/src/term.js
+++ b/src/term.js

       }
     }
   }
-  this.setupStops(j);
   this.cols = x;
   this.columns = x;
+  this.setupStops(j);

   // resize rows
   j = this.rows;
