* FIX: allow groups to access system queries (without having to run the query once first)
Bug is: Trying to allow a group to access a system query results in a Discourse::NotFound unless the query is run first.
Cause:
- System queries don't exist in the database by default
- update calls set_query before action
- set_query searches the database for the system query with Query.find_by(:id), which will not exist by default.
- running system queries first fixes this because Query.find is overridden to include system queries (Queries.default) in its results, avoiding the Discourse::NotFound.
Solution: use the overridden Query.find in set_query to include system queries in the search, instead of Query.find_by(:id)
* Added test for fixing allowing groups to access system query.
* Fixed test formatting.
Previously this was adding an extra AJAX request to check if the group had any queries available. Now a boolean is included in the group serializer, so there is no need for the extra request.
Removing this ajax request will also stop other plugin JS integration tests from failing when the data-explorer plugin is installed.
This commit also fixes the HTML markup of the tab, so that it doesn't have a <ul> nested inside the existing <ul>. Also adds an icon for good measure.
