Page saved to different location when destination in "Add" Dialog changed

[NicoHood]

Steps to reproduce:

• Open any page in admin panel
• Click "Add"
• Select a different folder
• Cancel the dialog
• Hit Save
• The page will be saved to that directory, but that should not happen. The add dialog should not be confused with the current page.

Another possibly related bug:

• Create a new page
• Save
• Click Add
• Select a different location
• Click Create
• A prompt will open, if you really want to leave the site, it has unsaved changes (but we saves all)
