fix(doctor): update broken command behaviour

[gavindsouza]

Bug: Change in behaviour of command
Command: bench doctor
PR: #10382
Why: Unlike other commands, doctor doesn't follow the behavioural pattern of currentsite being set. If currentsite is set and bench console, bench mariadb is run, the command will start for the current site, else you'll get a Please specify --site sitename error message. However, bench doctor does not follow this. After the aforementioned PR, this behaviour was broken. This PR reverts back to past behaviour.
