Fix chaperone profiles not loading correctly

Saving a profile with only visibility changed, the saved struct looks
like
bools\1\bools=false
bools\2\bools=true
bools\3\bools=false
bools\4\bools=false

The load function expects 2 bool values before loading
`includesVisibility`, leading it to getting a false value (actually
includesFadeDistance).

Making the struct save the `chaperoneGeometryQuadsValid` that it expects
to be saved there fixes the issue.

This bug highlights issues with the current object settings system, in
that debugging is unnecessarily tedious and difficult.
