[BUGFIX] Remove disabled button in inline records

If the info icon is disabled it is now removed completely.
Previously the logic for new records was not caught correctly, so that
the case for the enabled icon with a new record was executed.
Disabling the icon should remove it completely,
as a disabled non-clickable icon is not helpful and confusing for editors.
This is now done, and the case for the enabled icon with new records is
also correctly caught.
