Mis-handles a leading NOT clause

[fire-eggs]

If the first clause in the multi-filter is marked NOT, the query ignores the NOT.

I.e. in getImagesForTags2 the first clause is always generated as:

(select tag_id from tags where name like ?)

but when NOT is checked for the first clause, it should be:

(select tag_id from tags where name not like ?)
