(#14670) Fixup file_line autorequire specs

Without this patch applied the file_line autorequire examples are
failing.  This is a problem because the failures are false positives and
should be passing given the implementation.

This patch fixes the problem by changing the examples to directly test
the existence of the relationship by finding it in the list of
autorequire relationships.
