Remove slash from base url

[mogilvie]

The XeroPHP\Application\URL concatenates the Application config base_url with the path.

    /**
     * @return string
     */
    public function getFullURL()
    {
        $url = sprintf('%s/%s', $this->base_url, $this->path);

        return$url;
    }

resulting in a double slash after the base url. https://api.xero.com//api.xro/2.0/Journals?paymentsOnly=true&offset=33300.

Remove the trailing forward slash from the base_url.

@mogilvie Does this cause an issue with anything in particular? I know it's not correct, just can't think when/how it was introduced!

[mogilvie]

No, just identified it while I was resolving a different issue.

I'm going to leave this for a new version, as it's possible people are relying on that trailing slash.
