test: test that /packages/{name} produces the package's description

This commit fixes two of our tests in test_templates.py to go along
with our new template modifications, as well as a new test in
test_packages_routes.py which constructs two packages belonging
to the same package base, then tests that viewing their pages
produces their independent descriptions.
