Remove sample ignore list elements for coverage

The ignore list for coverage only has two test cases out of ~10000 that are
currently reported as not executed. This is a drop in the sea and not
useful. Remove them so that the class can be used generically. A follow-up
will construct a comprehensive ignore list.
