Add filter to exclude groupless jobs to API/V1

When trying to only exclude a specific group, it will still exclude all groupless jobs (this is why the second test i added still fails).
Is this maybe due to the comparison behaviour @perlpunk mentioned ?

Just a note, as we do not have groups with id 0, but null: this is turned into

WHERE ( me.group_id NOT IN ( 0 ) )

which works because in SQL, comparing something with null is always false, so any random number would work.

If i understand correctly then this should not be the issue here.
In the test data are 14 Jobs with the groupid 1001, one with groupid 1002 and three groupless jobs, so i would expect to get 4 jobs when excluding group 1001, though it returns only 1

Comparing somthing with null, even if it is a negative comparison, will always be false:

openqa=> select id, group_id from jobs where id = 4389101;
   id    | group_id 
---------+----------
 4389101 |         
(1 row)

openqa=> select id, group_id from jobs where id = 4389101 and group_id not in (23);
 id | group_id 
----+----------
(0 rows)

openqa=> select id, group_id from jobs where id = 4389101 and group_id != 23;
 id | group_id 
----+----------
(0 rows)

An additional or group_id is null would be necessary.

The circleci codecov problem still exists, it just doesn't run, and it's not possible to restart the workflow.

I will merge manually now.
