Internal link for just created note is not working/not available but UI allows to copy the internal link

### Expected
If 'Copy Internal Link' cell is enabled in 'Options', it should either work, or the cell should be disabled.

### Observed
For just created note, with no content yet, it's possible to tap 'Copy Internal Link' in 'Options' in note editor, but copying does not work

### Reproduced
> 1. Create a new note
> 2. Don't enter any text
> 3. While in note editor, open options (circle with 3 dots) and tap 'Copy Internal Link' ~> Internal link to this note is not copied

Reproduce the issue in the iOS note editor by creating an empty note and opening Options. Trace the “Copy Internal Link” action and the empty-note handling; done means the action either copies a valid internal link or is disabled when the note has no content.
