Motivation: When viewing a stack trace in YellowBox where one or more of the stack frames has no file, JS will encounter the fatal error null is not an object (evaluating 'file.split'). This can happen, for example, when running a bundle for which no source maps were generated.

Test plan: Send a stack trace with empty stack frames to console.warn, for example by turning off source maps.

I tried to merge this pull request into the Facebook internal repo but some checks failed. To unblock yourself please check the following: Does this pull request pass all open source tests on GitHub? If not please fix those. Does the code still apply cleanly on top of GitHub master? If not can please rebase. In all other cases this means some internal test failed, for example a part of a fb app won't work with this pull request. I've added the Import Failed label to this pull request so it is easy for someone at fb to find the pull request and check what failed. If you don't see anyone comment in a few days feel free to comment mentioning one of the core contributors to the project so they get a notification.
