does not use dbus.Struct.signature to guess signature of a Struct

Description

import dbus dbus.lowlevel.Message.guess_signature((42,)) dbus.Signature('(i)') dbus.lowlevel.Message.guess_signature(dbus.Struct((42,), signature='u')) dbus.Signature('(i)')

The second one should clearly be dbus.Signature('(u)').

Workaround: use a tuple containing fully-qualified dbus types:

dbus.lowlevel.Message.guess_signature((dbus.UInt32(42),)) dbus.Signature('(u)')

Arrays work fine either way:

dbus.lowlevel.Message.guess_signature([42]) dbus.Signature('ai') dbus.lowlevel.Message.guess_signature(dbus.Array([42], signature='u')) dbus.Signature('au') dbus.lowlevel.Message.guess_signature([dbus.UInt32(42)]) dbus.Signature('au')
