Exception on time out

[bwilkerson]

I don't know whether this bug is also in the test package, but I found it while debugging a failing test. Operating at human speed caused the test to time out, producing the exception below.

I was running on my Mac, using a bleeding edge build. The DartDoc for the request getter explicitly states that it can return null, but the code doesn't check for null. (By the way, the DartDoc contains a typo at "has is".)

Unhandled exception:
The null object does not have a method 'toUpperCase'.

NoSuchMethodError: method not found: 'toUpperCase'

It looks like this is an issue with unittest 0.11.x, which is no longer officially supported. I bet if you upgrade to 0.12.x, this'll go away.
