fix: solid fields should not render every field on keystroke anymore

[crutchcorn]

Thanks to a conversation I had with @KevinVandy I noticed that our Solid adapter was causing unintentional re-renders of all form.Fields in Soild.js only - this PR fixes that by doing more referential checking on the base store.

Now things go brr.
