Fix saving changes in NoteEditor after CardTemplateEditor visit

[lukstbit]

Purpose / Description

After going to CardTemplateEditor the current card being edited is fetched again from the collection(this makes the card to have a null Note). After making changes and attempting to save, in the saveNote() method the card's note is being accessed and because it's null a call to note(collection) is done. This call fetches the previous stored fields values and those values end up being saved instead of the changed ones.
