chore(deps): update localforage to ~1.6.0

This Pull Request updates dependency localforage from ~1.5.5 to ~1.6.0

Release Notes

### [`v1.6.0`](https://github.com/localForage/localForage/releases/1.6.0) Adds `dropInstance()` method to localforage. This will be an optional method for custom drivers to preserve compatibility in an effort to not make this a breaking change. Custom driver that doesn't provide the `dropInstance()` method will reject with a respective error when this method is invoked. Further improves IDB driver reliability by trying to reestablish closed connections or upgraded stores. ---
