Uncaught exception logic is faulty.

While attempting to add a means of signalling an exception generated outside the context of a test to Whiskey, I happened upon another bug with respect to exceptions within the context of a test.

To reproduce:

1. Edit lib/common.js and insert this text on line 425: throw { message: 'hello world' };
2. Invoke Whiskey (see results below for how I invoked it).

Apparently, the _testObj member of the TestFile class is not being initialized.

$ NODE_PATH=$(pwd)/lib-cov bin/whiskey --coverage --coverage-reporter cli --coverage-file /tmp/hooey --coverage-dir /tmp -t example/test-bdd.js                                                                                                                                                                   /Users/sfalvo/git/whiskey :: Mon Jun 10 15:32:34 PDT 2013
path.existsSync is now called `fs.existsSync`.
/Users/sfalvo/git/whiskey/example/test-bdd.js

Stderr:

/Users/sfalvo/git/whiskey/lib/common.js:553
    test._testObj.finish();
                  ^
TypeError: Cannot call method 'finish' of null

@sam-falvo Can you please provide a link to the line in a file where this happens / patch which reproduces this?

Also, judging by the exception this doesn't seem to happen in the context of a test, although I might be wrong.
