Crash related to UIPageViewController

[valeriy-kolodiy]

After updating Instabug iOS SDK from 10.7.3 to 10.10.1 app crashes when calling the setViewControllers method on the UIPageViewController instance.

Crash is not reproducable after setting the Instabug.reproStepsMode = .enabledWithNoScreenshots.
That actually fixes the issue for us, but still would be great to have it fixed on the SDK level.

Looks like that's the same crash that was reported before:
Instabug/Instabug-iOS#230

Crash does not happen when downgrading back to 10.7.3 version.
Looks like the crash was introduced in SDK version 10.8.0

Hi @valeriy-kolodiy,

Thank you for reporting this. I tried to reproduce the crash by creating a new project that has a UIPageViewController and I also used setViewControllers. However, I wasn't able to reproduce. Here's a link to the repo https://github.com/HassanElDesouky/UIPageViewControllerInstabugCrash

It'll be very helpful if you can create a demo project that reproduces the crash or just point out what I'm missing in mine.
