Remove nullchecks for NavigationController::GetLastCommittedEntry() etc

NavigationController's GetLastCommittedEntry(), GetVisibleEntry() and
related functions used to be able to return nullptr when no
navigation had committed. However, with InitialNavigationEntry
enabled, those NavigationControllers would have at least 1
NavigationEntry, the initial NavigationEntry, and those functions
will not return nullptr.

This CL updates documentation for those functions and removes code
that handles the null case, as they are not needed anymore.

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.
