st/password-entry: Fix crash when DConf changes after StEntry is destroyed

commit 8721c5db37 made StPasswordEntry
honor the 'disable-show-password' setting.

Unfortunately, it introduced a lifecycle bug where the signal handler
for noticing setting changes can out live the entry itself.

This commit fixes the problem by using g_signal_connect_object
