Reset atoms no longer remove from local storage

[caviyacht]

It appears that Recoil 0.4.0 introduced a breaking change around how the DefaultValue and effects work. The onSet method no longer gets the DefaultValue when reset, but instead an actual value. The logic to remove the key from local storage was dependent on this.

Update to this. I mentioned on the Recoil repo that it appears to function correctly if you use a selector as the default value to an atom. I've switched to using this for now, but it seems like that might not stay as well.

@polemius , Recoil 0.5 was released with an enhancement to this area. isReset can now be used to know if an atom was reset in an effect.

Thank you! New resetting atom logic was just released in 4.0.0.
