Check for missing endpoints when adding assocs

An association links 2 D-Bus object paths together, one
which is the path that has the original associations
property, and another endpoint path.  It's possible that
that endpoint path doesn't exist on D-Bus when that
associations property is created.

This commit, along with upcoming ones, adds support to not
create the actual association object paths until that
endpoint path shows up on D-Bus.  In addition, if that
endpoint path were to get removed from D-Bus in the future,
then the association paths should be removed until that
path is back again.

This particular commit introduces the PendingAssociations map
to track these cases, and adds support in the associationChanged
path to add associations to this map if the endpoint path isn't
on D-Bus instead of just blindly creating the association objects.
