fix: disable the text search when filtering by drafts - MEED-10296 - Meeds-io/meeds#3917 (#702)

Prior to this change, when searching for news using a text query and
selecting the drafts filter, the results returned were posted articles.
This issue occurs because only news articles are indexed, making text
search for drafts not possible. This change will disable text search
when the drafts filter is selected.
