Describe the bug

When as an Admin you try to delete a Sector type already link to a process you have a SQL error displayed.
The error is due to foreign key constraint violation.

To Reproduce

1. As Admin go to 'Settings'
2. Create a sector type
3. Create a sector for the previous sector type
4. In a process go to the Filters section, check the enable scope
5. Select a Scope in the scope dropdown list
6. Select a Scope type in the Scope filter depth dropdown list
7. Save the Process
8. Go back to 'Settings'
9. Try to delete the Scope type you linked to a scope in the previous Process
10. See error

Expected behavior

The user should be displayed a message that said he can not delete the sector type because it is already link to a process.
The message error text should be in a yml file for translation purpose.
Or when a Scope type is linked to a process the delete button should not be clickable or displayed for this Scope type.
