GTasks: Google tasks not shown in scheduled list

[marbetschar]

What Happened

Tasks with due date from the Google backend are not shown in the scheduled list. This has two potential solutions:

1. The EDS version used is only capable to query for has-start?. The has-due? s-expression is not yet available (will be in EDS 3.39.1+)
2. EDS converts tasks from GData.TasksTask to ICal.Component and does not set the start date in this conversion

Solving either of these problems would allow to show GTasks in the scheduled list. But in both cases a newer EDS release is needed. Therefore the first solution would be preferred and may be achievable by bundling a newer EDS version within Flatpak.

Expected Behavior

All tasks with due date should be shown in the scheduled list - incl. GTasks.

EDS 3.40 is out, and it looks that it doesn't break the DBus api, so we can use it, I'll make a PR updating the flatpak manifest

Bad news, we can't use has-due, the query runs on the system EDS, I think the same is happening with #192.

This issue also seems to affect CalDAV tasks that don't have a start date set.
