PHP error notice: Trying to get property of non-object in content_taxonomy_autocomplete_merge_tags()

Hi there,
I use Drupal 6.26 with Content Taxonomy 6.x-1.0-rc2

When viewing a node form utilising content_taxonomy and having autocompletion enabled, the following error notice shows up in my watchdog:

error php notice: Trying to get property of non-object in content_taxonomy_autocomplete_merge_tags() (line 406 of /var/www/data/drupal6/sites/all/modules/content_taxonomy/content_taxonomy_autocomplete.module

Proposed solution: Check if $term is not empty before trying to access $term->vid
