fix(status): enable --booted option to only show the current deployment

The existing code didn't take into account the --booted options, so always
showed the staged, current and rollback deployments.  This correctly
wires through the --booted option to only show that deployment.

Stubs have been left in the code should we wish to enable options to show
only the rollback or staged options (--rollback / --staged).

No docs changes were required since the flag is already present.

Closes #465
