SSH: Don't use providers in commands

SSH commands are created in request scope. That why it's not needed to
use providers for current user and review db, that are also provided in
the same scope. Providers are needed when data is used across scope
boundaries, e.g. PatchSetParser that is bound in singleton scope must
use providers to access current user and review db.
