Craft error when editing CKEditor field after assigned CKEditor config is deleted

[mprofitlich]

Description

When a CKEditor config is deleted, the fields that use this config will not be editable anymore. Opening them will produce the error "Invalid CKEditor config UUID: [uid]". This totally makes sense but makes it impossible to repair the field. Better would be to allow for the selection of another CKEditor config.

Steps to reproduce

1. Create a field of type CKEditor
2. Assign a CKEditor config
3. Delete the CKEditor config
4. Try to edit the field crated in step one
