Fix settingsd core dump/persistence fail
The problem was seen only with network settings objects, because they
had paths as following:
A setting d-bus object /foo/bar/baz is persisted in the filesystem with
the same path. This eases re-construction of settings objects when we
restore from the filesystem. This can be a problem though when you have
two objects such as - /foo/bar and /foo/bar/baz. This is because 'bar'
will be treated a file in the first case, and a subdir in the second.
This was causing an exception to be thrown by Cereal, because it found a
dir where it was expecting a file. This also caused us to not persist
certain network setting objects because we couldn't create subdirs
as there were files of the same name.
To solve this, suffix files with a trailing __. The __ is a safe
character sequence to use, because we won't have d-bus object paths
ending with this. With this the objects would be persisted as -
/foo/bar__ and /foo/bar/baz__.
