fix(test): test data outside folders will not be loaded by MSSDK

Fix the test assumptions by reducing the number of test data to match.
In the case of the Standard Forms (v1) package `package_F03_test`, there
are 105 test data files, of which 82 are unique. However, only 81 of
them are to be found within folders under `test_data`, whereas the rest,
including a unique one `example.xml`, is not contained within a folder.
