Address ActiveRecord deprecation warning

AR will start to complain about eager loading in command_dispatcher
/db.rb:519 because it references hosts as string without explicitly
stating that the table is being referenced.

Add a call .references in the AR call chain after the where clause
to silence this abysmal warning.
