Test: Clean up and fix misc issues

* Clean up testinit and testrunner

* Uncomment isLocal (at least make sure it is declared)

* Rephrase environment assertions to make sense if one reads
  them when they pass.

* Optimise an expensive loop that might be the cause of this
  in IE6: http://cl.ly/image/3f20053m112n
