[ios] Attempt to fix race condition in ReauthenticationCoordinator

The crash stack seems to indicate that we're trying to pop the reauth
view controller before it is fully pushed into its navigation
controller. This patch tries to fix the issue by delaying reauth until
the reauth view controller is fully presented. From a UI perspective
the change is not very visible ( auth is triggered milliseconds later).

I also changed a DCHECK to a non fatal CHECK until milestone 135 to
monitor the issue on stable.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure.

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.

If you found a bug, please file it at https://crbug.com/new.
