Make the unit test runable without requiring composer

[scottchiefbaker]

Currently the unit tests fail if you don't install bugger via composer

Warning: require(/var/www/html/scott/tmp/bugger/tests/../vendor/autoload.php): failed to open stream: No such file or directory in /var/www/html/scott/tmp/bugger/tests/bootstrap.php on line 2

Fatal error: require(): Failed opening required '/var/www/html/scott/tmp/bugger/tests/../vendor/autoload.php' (include_path='.:/usr/share/pear:/usr/share/php') in /var/www/html/scott/tmp/bugger/tests/bootstrap.php on line 2

As the vendor directory isn't present if you don't use composer to install.
