Odd interaction between `showOuterLonePairsProperty` and `showLonePairsProperty`

[arouinfar]

Related to #223, and relevant history of showOuterLonePairsProperty can be found in #194 and #201.

Steps to reproduce:

1. Open Molecule Shapes in Studio.
2. Go to Real Molecules screen and select BrF5, since it has lone pairs on the central and outer atoms.
3. Set showOuterLonePairsProperty to true. Outer lone pairs appear as expected.
4. Set showOuterLonePairsProperty to false. All lone pairs disappear, including the one on the central atom. (The central lone pair should be independent of the outer lone pairs.)
5. Uncheck the Show Lone Pairs checkbox, then turn it back on. The lone pair reappears on the central atom, but a few outer lone pairs also show up.

@jonathanolson unfortunately this isn't consistent. I have two different tabs open in Chrome -- in one tab, I cannot reproduce this at all. In the other tab, I can consistently encounter the described buggy behavior.

Here's the troubleshooting info for the phet-brand version on master:

For https://github.com/phetsims/qa/issues/844 this also happens in the PhET brand sim.

Adding on to what Nancy saw, just turning the "Show Lone Pairs" off and on again does this, you don't need to turn outer pairs on or off from what I saw.

[Nancy-Salpepi]

I saw the same as @KatieWoe-- no need to do steps 3 and 4 to see the outer lone pairs appear when they shouldn't.

The other part of the bug that was reported by @arouinfar also happens in the PhET brand sim: Checking and unchecking the Show Outer Lone Pairs Checkbox also hides the lone pairs for the central atom when it shouldn't.

Also the bugged pairs seem different when you are in projector mode. Non projector mode: Projector mode:

Fix applied in common code above. Closing.
