gdbus: Check signature of NameAcquired, NameLost

Calling g_variant_get (parameters, "(&s)") when parameters has a
signature other than (s) is considered to be a programming error.
In practice the message bus (dbus-daemon or a reimplementation) should
always send the expected type, but be defensive.

(Modified by Philip Withnall to improve type check.)
