[Koha-patches] [PATCH] [SIGNED-OFF 3/3] Bug 5392 Initialize vars used in building url strings

[Galen Charlton]

From: Colin Campbell <colin.campbell at ptfs-europe.com>

If no failures are to be added to the to the strings for redirect
the corresponding variables are undefined causing warnings
to be logged. Initialize them so that the error log is not
being filled with trivia.
