Small description of change:

Fixes issue where

phalcon create-controller --name test

defaults to NULL as the directory where it searches for the config.php file in the wrong place, /, upon not finding it, the code falls back to a recursive directory search logic which then finds the public/webtools.config.php file and loads up the wrong config file causing an error:

PHP Fatal error: Uncaught Error: Call to a member function path() on int in /var/www/repos/phalcon-devtools/scripts/Phalcon/Builder/Controller.php:74
Stack trace:

#4 {main}
thrown in /var/www/repos/phalcon-devtools/scripts/Phalcon/Builder/Controller.php on line 74

This can be worked around with:

phalcon create-controller --name test --directory .

but the code should not error when not specifying a directory.

Thanks
