BaseError fails to handle null response

[quinncomendant]

BaseError::__constructor expects its second argument $response to be an array with specific values. The $response argument will be null if the server produces a HTTP 500 Internal Server Error, and the following php errors produced:

PHP Warning:  array_map(): Argument #2 should be an array in /var/www/lib/vendor/basecrm/basecrm-php/lib/Errors/BaseError.php on line 21
Warning: array_map(): Argument #2 should be an array in /var/www/lib/vendor/basecrm/basecrm-php/lib/Errors/BaseError.php on line 21
PHP Warning:  implode(): Invalid arguments passed in /var/www/lib/vendor/basecrm/basecrm-php/lib/Errors/BaseError.php on line 21
Warning: implode(): Invalid arguments passed in /var/www/lib/vendor/basecrm/basecrm-php/lib/Errors/BaseError.php on line 21

It also seems a useful exception is not raise.

I don't know how to fix this, I just wanted to note that it can happen.
