Groups Array contains duplicates after multiple reloads/changes of virtual groups

[einhirn]

I found out that the virtualgroup plugin adds the virtual groups for a user again and again and again. Check for yourself by adding a group via virtualgroup plugin and then "do=check". Reload. Reload...

Anyway: This is the patch - it just adds "array_unique" around the "array_merge" (in case the patch fails for any reason):
