Fallback to operation without rclextract fails

[bheorcnh]

Due to a wrong wsgi user configuration, the line from recoll import rclextract threw an exception as a result from mkdir(/usr/share/httpd/.recoll) failed: Permission denied This is correct behaviour until here. But as a result import recoll was called in the exception handler instead of from recoll import recoll This resulted in an error AttributeError: 'module' object has no attribute 'connect', later in line db = recoll.connect(config['confdir']) where it is difficult to find the reason for.
