"Path already exists." when reusing path for vocabulary

When you have set up a vocabindex path for one of your vocabularies and when you want to submit the path setup from again, for instance when you have set up a path for another vocabulary, the old paths would cause errors, because there was a bug in checking whether a path was already in use by his vocabulary. This issue matches the code in vocabindex.admin.inc at lines 102 and 103:

Old:

$result=db_result(db_query("SELECT vid FROM {vocabindex} WHERE path = '%s'", $path));
$message=vocabindex_check_index($result->vid, $path);

New:

$vid=db_result(db_query("SELECT vid FROM {vocabindex} WHERE path = '%s'", $path));
$message=vocabindex_check_index($vid, $path);

This issue has been fixed and will be committed to CVS right away.
