Xavier Noria ae07806858 fixes circularity check in dependencies
The check for circular loading should depend on a stack of files being
loaded at the moment, rather than the collection of loaded files.

This showed up indirectly in #16468, where a misspelled helper would
incorrectly result in a circularity error message.
