Some tray items re-register the same bus name and object path during normal
operation. Treat that path as an idempotent registration instead of logging a
warning, while still completing the DBus method successfully.

Return the host registration method correctly on duplicate host registration
and emit HostUnregistered instead of HostRegistered when the last host
vanishes.
Also free the corresponding name watch once the tracked host/item disappears so
the watcher does not leak stale watch records.

This reverts commit 2d33c20231 and
reapplies various patches for memory leaks.
The reason for the revert was a bug for a maximum duration interval
which caused sleep_for() to cause unpredictable behavior.
After upgrading to the latest release of Waybar the bar will crash
whenever I close the laptop lid. After some debugging I believe it is
because the watching added by watch_name is not being correctly canceled
using unwatch_name. After the Tray object and Host object are destroyed,
additional callbacks will become use-after-free.
Looks like commit 3af1853260 removed the
unwatch_name. I'm not sure why it did that, but it seemed dangerous.
Additionally, bus_name_id_ is created by own_name. According to that
function's documentation, the correct inverse operation is unown_name.
