Florian Müllner 358133e82f Initialize properties in _init()
While we've always considered it good style to initialize JS properties,
some code that relies on uninitialized properties having an implicit
value of 'undefined' has slipped in over time. The updated SpiderMonkey
version used by gjs now warns when accessing those properties, so we
should make sure that they are properly initialized to avoid log spam,
even though all warnings addressed here occur in conditionals that
produce the correct result with 'undefined'.
