Code review comment for lp:~xavi-garcia-mena/indicator-sound/restart-dbus-error

Although the approach in this branch is not ideal I'm implementing the workaround like this to wait for dbus session connection to be ready.

This might happen to any indicator, but is more easy to recreate for the sound indicator as the very first thing the indicator does is to try to acquire its dbus name.

I've opened a separated bug for this:
https://bugs.launchpad.net/upstart/+bug/1525183 in which the root issue should be fixed.

I've also like to note that the issue will be probably fixed when we move to systemd.
The idea would be to rollback this branch when the switch to systemd is done.
