Solr base query adds an extra slasj in getPath() when there is no 'q' param

Hi,

I have a request of code addition so the apache solr views module facets work fine, this is the fix that the module needs to remove so extra slashes generated when the solr query has a path as in the case of a view in the apachesolr.module getPath function.

public function getPath($new_keywords = NULL) {
    if (isset($new_keywords)) {
      return $this->base_path . '/' . $new_keywords;
    }
    if($this->getParam('q')) {
      return $this->base_path . '/' . $this->getParam('q');
    }else {
      return $this->base_path;
    }
  }

Thank you in advance.
