Alternative build systems like blaze don't always provide a way to determine
the relationship between a package and the package it's testing. This means
that sometimes the check for misspelled Example function names over-reports
because it doesn't find the object being exemplified. Don't report errors
unless a object can't be found in any of the imports. This means that there
won't be any false positives though of course this comes at the cost of
false positives.
