async: proxy: fix property sub-proxy initialization
The proxy's Service and Path are either a string_view or string,
depending on the Preserved template parameter. If the constant
`dbus_prop_intf` is a string_view but Preserved=True, there is no
implicit conversion from string_view to string, so the construction
of the sub-proxy fails. Use `auto` (as C-string) to allow
automatic implicit conversion to both string_view or string depending
on the Preserved value.
