Path intersection was not checking paths with circles. (#1229)

As an optimization the path intersection was checking the paths had three or more elements, caliming that otherwise there was nothing to fill. However a semi circle would actually contain 2 points. Fixes #1048. This adds a simplified test case for the 2 offending files reported in the issue.
