Before this fix, creating a project with Typesense enabled would fail with an error because the tasks it fetches as part of that process do not have the task position property in their index. We now fall back to using the db for searching in that case.
In the long run, we should use typesense joins for the task position to make this more efficient.
BREAKING CHANGE: the position of tasks now can't be updated anymore via the task update endpoint. Instead, there is a new endpoint which takes the project view into account as well.
