Philip Withnall ccbb2d8e8a gdbusnameowning: Subscribe to NameLost before calling RequestName
There was a slight race in name ownership: a gap between calling
`RequestName` (or receiving its reply) and subscribing to `NameLost`. In
that gap, another process could request and receive the name, and this
one wouldn’t know about it.

Fix that by subscribing to `NameAcquired` and `NameLost` before calling
`RequestName`, and then unsubscribing again if the subscriptions turn
out not to be necessary (if the process can’t own the requested name).

Spotted and diagnosed by Miika Karanki.

One of the tests needs an additional iteration of the main loop in order
to free all the signal closures before it can complete its checks.
