[ticket/10407] Fix check for empty image paths in convertor

This applies to avatar_path,avatar_gallery_path,smilies_path and
upload_path.
Currently, the convertor gets each path from the config table and adds a
trailing slash. If there is no entry in the config table for the path, the
path can never be empty because of the added trailing slash. This patch
will temporarily remove the trailing slash, then check if the path is
empty.

Currently, the convertor gets each path from the config table and adds a

will check the path without the trailing slash to see if the path is
