Bug 746873 - Gnucash asks sql passwords before wallet password

Work around a bug in libsecret. Under certain conditions
libsecret will silently fail to find a password even though
it is stored. The workaround uses another interface call
to force unlocking the secret store which works around the bug.
This workaround should be removed once a fix for
https://bugzilla.gnome.org/show_bug.cgi?id=748625
will be commonly available.
