Update kdewallet to 1.3.2

[purejava]

Closes cryptomator/cryptomator#3020.

Up to version 1.3.1 of kdewallet, the code contains a shutdown hook, that gets triggered on shutdown of the JVM and performs a clean-up.

This clean-up unregisters the D-Bus signals relevant for and registered to kdewallet.

Nevertheless, the clean-up can fail when the D-Bus connection is already closed.

Furthermore, the clean-up is not needed, as dbus-java does the clean-up.

This PR updates the dependency to kdewallet 1.3.2, where the shutdown hook and the clean-up were removed.
