Can't add a task to a remote project.

[fboudry]

When trying to add a task in a remote project/list (i.e any Nextcloud project for me) I'm being stuck on the task add popup and can only exit it.

To Reproduce
1 - Click on "add"
2 - Enter tasks informations
3 - Click on "Add To-Do"
The processing wheel is shown but the popup stays and the task isn't added.
No error is shown when launched through a console.
This error does not occur when using another task manager, and the synchronization is working.

Expected behavior
The task is being added to the selected list.
(The normal behavior is observed in any project that isn't synchronized.)

Desktop :

• Archlinux/KDE
• Plannify 4.11.4
