Constant size checkbox saving of state

Test device Dell Operating System Win 10 Browser Chrome Problem description Offshoot of https://github.com/phetsims/collision-lab/issues/183. Requested in https://github.com/phetsims/collision-lab/issues/183#issuecomment-757093430. The state should probably be changed when the constant size checkbox is checked or unchecked, as it changes when and where two orbs will bounce off each other meaning that stepping back past that point can lead to a slightly wrong history. This is less drastic than other instances of this wrong history, but it is still there. Interestingly, while stepping back with the step back button takes you past the change point, the blue restart button does take you to the point where the checkbox was checked.

Thanks @KatieWoe. That definitely looks a bit strange.

@jonathanolson would it be hard to add toggling the Constant Size checkbox to the laundry list of things that triggers a new saved state?

I believe this should be handled with the above commit, can you verify?

Looks good after a quick check on master
