Fix converting dbus.UInt types to string

With Python 3.8 converting these directly to string using str()
no longer works, we need to convert these to integer first.

On Python 3.8:

>>> str(dbus.Int64(1))
'dbus.Int64(1)'

On Python 3.7 (and older):
>>> str(dbus.UInt64(1))
'1'

This is probably related to removing __str__ function from method
from int (dbus.UInt is subclass of int) which happened in 3.8, see
https://docs.python.org/3.8/whatsnew/3.8.html
