…ion#399)

* Allow Monkey used injector to generate CRISPR Charge (tgstation#65552)

Changed DNA Console behavior so it will accept unfilled dna injector, allowing use of monkeys to generate a CRISPR charge, as per Wiki Genetics Guide statement that this should be possible.

Fixes CRISPR charge to not be added despite the message saying so.
