let the close button reflect the page_complete status of SUMMARY pages

Fixes: https://bugzilla.gnome.org/show_bug.cgi?id=604289
In order to respect this properly, we have to restore the original
behavior by watching a flag to check if the user has already set this.

* gtk/gtkassistant.c: fix the bug by introducing a flag to check for
  non-automatic value setting
* tests/testassistant.c: updated the "generous assistant" to permit
  quick manual testing of this feature
