Made the SpeciesChange mutation no longer transfer with Sterile Swabs. (#33126)

Made the SpeciesChange mutation no longer persist.

There was an issue where swabbing a mutated plant species: I.e Blood Tomato to a regular Tomato sapling would transfer the species mutation. It would not actually get the effect, which is probably why it went under the radar. This change makes it so that the SpeciesChange mutation cannot be transferred via swabbing.
