Description

Task objects are now updated if the frontmatter in the file containing them is edited.

Motivation and Context

This fixes an unreleased bug, that editing properties/frontmatter did not update Tasks query results. This matters now that properties/frontmatter can be used in Tasks queries.

The steps to reproduce the bug are:

1. Install development version of Tasks plugin
2. Create a note called test
3. Paste in this content:

---
custom_number_prop: 42
---

```tasks
path includes {{query.file.path}}
group by function task.file.property('custom_number_prop')
```

- [ ] #task Hello

4. Preview the results. It should show this:

5. Use the 'File properties' panel to edit the property value from 42 to 43

Expected result

Group heading changes to 43:

Actual result

Display is unchanged until edits are made to the task line in the file, or Obsidian is restarted.
