Fixes unexplainable and esoteric Byond-exclusive bug that has no reason to exist and syntactically shouldn't even change anything
requested to merge pull/4957/incomprehensibleunexplainableprofaneredundantsyntaxnecromancy into Bleeding-Edge

Fixes #4946 (closed) Clusterfack told me to change all other mousedroppable medbay machines to have the same syntax but then THOSE begin to runtime for no seeming reason if you add the redundant .src, so I just don't fucking know. The body scanner is the only one that runtimes in this very specific fashion. Just leave everything the same and hope it doesn't inexplicably break again
