Some actions in split modulestore record the user ID who requested the action. Currently, split modulestore doesn't care what data type you use for those user IDs. Most of the codebase uses integers, but some tests used username or email address strings. My upcoming PR #27565 will move split modulestore's "course index" data from MongoDB into MySQL. In doing so, it requires that user IDs are always numeric. So this PR paves the way for that one by using numeric IDs consistently in all test cases. I believe the actual non-test code was already consistently using integer IDs.
