Remove unsafe-paths test obsoleted by hex_core 0.16.0

hex_core 0.16.0 validates paths at the public API boundary in both
:hex_tarball.create_docs/1 and :hex_tarball.unpack_docs/2. The test
relied on create_docs accepting unsafe paths so it could exercise the
unpacker's rejection. With validation now enforced at create, the case
the test covered is no longer reachable through the library's contract.
