Matthias Clasen 64b9114d98 password entry: Fix property notification
Both placeholder-text and activates-default were not
up to our usual standards for property notification,
and the tests complained.

* SECTION:gtkpasswordentry
* @Short_description: An entry for secrets
* @Title: GtkPasswordEntry
*
* #GtkPasswordEntry is entry that has been tailored for entering secrets.
* It does not show its contents in clear text, does not allow to copy it
* to the clipboard, and it shows a warning when Caps Lock is engaged.
*
* Optionally, it can offer a way to reveal the contents in clear text.
*
* GtkPasswordEntry provides only minimal API and should be used with the
* #GtkEditable API.
