Correctly reset slave status when aborting a registration.
Previously, the slave was not erased from the \`registering\`
and \`reregistering\` sets in the master for some code paths
that would result in a failed (re-)registration attempt.
This could lead to a state where the reason of the unsuccessful
(re-)registration attempt is fixed on the agent, but the master
ignores subsequent attempts because it assumes the previous
operation is still in progress.

> Agent can become stuck in (re-)registering state during upgrades

>
> Currently, an agent will not be erased from the set of currently
> (re-)registering agents if
> - it tries to (re-)register with a malformed version string
> - it tries to (re-)register with a version smaller than the minimum
> supported version
> - it tries to (re-)register with a domain when the master has no domain
> configured
> - the operator marks the slave as gone while the (re-)registration is ongoing
> Afterwards, all further (re-)registration attempts with the same agent id
> will be discarded, because the master still thinks that the original
> (re-)registration is ongoing.
> Since most realistic way to encounter this issue would be during cluster
> upgrades, and it will fix itself with a master restart, it is unlikely to be
> reported externally.
