Fix pelias results archiving functionality

Pull in latest pelias release?

We are currently testing different MapViews with Xcode 9 and can't use this SDK because of an issue in the pelias dependency:

Is related to #341

[msmollin]

Interesting - yeah we're aware of that issue but it's not causing compiling errors for us in our Sample App. Can you possible share some implementation code?

We fixed it as part of the Swift 4 migration for Pelias however we then ran into the linked cocoapod issue in #341, so we've been holding off on upgrading Pelias in the main SDK until that cocoapod issue got resolved and the subsequent PRs merged.

If it's causing you issues we can revert the Swift 4 migration and patch it in Swift 3.x.
