If a class is declared in multiple modules, the standalone migration may end up generating invalid code. While declaring a class in multiple modules is an error, it can happen with modules in tests. These changes avoid the issue by using a Set to track the classes being migrated.

Note that I didn't add a test for this case, because the way the string buffer works from the CLI means that the two conflicting edits of the same class are valid. This issue came up internally where we use a different way of manipulating strings.
