Sync settings enabled even if sync server configurations are not set

### Describe your issue

user should not able to toggle Sync Settings without first configuring TaskServer.
In my opinion the sync settings should be disabled if config of any one taskServer is not set,And prompt user to set them

### Steps to reproduce

_navigation_
1.open the app
2.click on menu (top right)
**IMPORTANT** -remove, if any previously created profile/taskServer (remember you cant remove default "New Alias")
3.Click on settings
4. And you will able to set sync on Start and Sync on task create (again which should not be allowed if taskServer configs are not set to import user experience.

### What was the expected result?

Should prompt user to set profile/taskServer

Start at the app's Settings screen and trace the Sync on Start and Sync on task create controls back to the TaskServer/profile configuration. Reproduce the flow after removing non-default profiles, then verify that unavailable configuration disables the controls or prompts the user to configure a TaskServer.
