Title: Stringify the $guid before trying to load

XML::XPath is returning XML::XPath::Literal objects instead of normal strings.
In MT4 it was not a problem, as it was ignored and accidentally was stringifyed somewhere in the lower levels, but in MT5 it isn't and is converted to empty string.

The end result is that entries are created again and again.

This patch stringify the value before passing it to load.
