Update problem-builder to version 2.0.3

[omarkhan]

Bug

The 'Download report' link on the problem builder dashboard is currently broken. Images are not always displayed, for 2 reasons:

• If the image is from a different domain and it has been cached by the browser, it is not converted into a data URL due to cross-domain security issues. A javascript SecurityError is thrown, and nothing happens.
• If the image url starts with // (no explicit protocol) or the url is relative (e.g. /static/...), and it has not yet been cached by the browser, it will fail to show up in the downloaded report.

Fix

These issues have been fixed in version 2.0.3 of problem builder (see open-craft/problem-builder#106). This pull request updates edx-platform to use the new version.
