[Instantsearch] Update selected refinements

[Jade-GG]

By matching the items to the actual filter data we can:

• Check if it's a boolean and show the proper label
• Get the actual filter name so we don't have to show the filter code

I've also updated the "clear filters" to match the old one, and used v-show instead of v-if to not need the empty div in the v-else.
