Sixth arg DEFAULT-VALUE is the default value. If non-nil, it is
available for history commands; but, unless READ is non-nil,
`read-from-minibuffer' does NOT return DEFAULT-VALUE if the user
enters empty input! It returns the empty string.

You can just test for "", or use read-string:
Fourth arg DEFAULT-VALUE is the default value. If non-nil, it is
used for history commands, and as the value to return if the user
enters the empty string.
