iOS app crashes when switching tours

[jollopre]

Anytime a tour is switched and the user taps on any marker, the app crashes.

Scenario:

• Open the app with the default tour
• Change tour
• Tap any marker

It might be related to #95

I think this issue was fully fixed in my pull request, even though it might be good to check on iPhone, since I could only test it on Android.

Adrian, I'm afraid this is still an issue on iOS - have just tested and confirmed this. Happy for you to use my phone to view and then test the fix.

[adrianczuczka]

I see, then that would be great, as I don't have an iPhone at my disposal.

I added another commit to fix a problem with setting markers' zIndexes, and it should now correctly update them. Again, it is probably good to try it on iPhone but it does work on Android. My changes are in my fork, in branch "issue-102-app-crashes", so you can clone that and try it. I'll also open an issue regarding the back button functionality on Android (and workarounds on iOS) if that's ok.

@adrianczuczka @jollopre I presume we will we need to issue a new app update to get this onto our users devices?

[adrianczuczka]

We might want to wait a bit because I'm working on the UI right now, so if you guys will agree with the changes I'll make, we can issue a big update rather than many small ones

This has been tested again in Test Flight and the crashing persists.
