Test coverage does not cover specified use cases

	my_software.find_metadata()
	assert my_software.citation_plain == expected

The general test coverage designated above, for the items generated in production_tests.py (I think?), doesn't cover all of the use cases specified on the website.

Namely, I was thinking about cases where simply the name of the package was typed in, for example 'numpy', 'pandas', or 'scipy'. I would expect that to be a fairly common use case, no? Currently it seems that only one of those cases ('scipy') works reliably.

Also, great tool! Hope it achieves success.
