Cannot add taskc tasks

### Describe your issue

After enabling `Taskchampion sync`, I am unable to create new tasks.

Current debug build: 1fe609a

### Steps to reproduce

1. Do a fresh `--debug` APK install
2. Change `Taskchampion sync` to true
3. Press "+" button and enter a task description
4. Click "Save"
5. `Task Added Successfully!` snackbar appears, but no task has been created

### What was the expected result?

A task to be visible on the home page

### Put here any screenshots or videos (optional)

No file or test is named. Reproduce the failure on a fresh --debug APK with Taskchampion sync enabled, then trace the + button and Save flow through task creation and sync; done means the success snackbar is accompanied by the new task appearing on the home page.
