[pass] [PATCH] Substitute empty string for None

[Andrew Spiers]

If keepassx2pass.py is given an xml file containing passwords with an empty
title, like <title></title>, ElementTree.text returns None. This commit
substitutes an empty string; which will produce a password with name '_',
instead of raising AtttributeError, as shown in this exception::
