Test fails because s-yata/marisa-trie removes MARISA_FORMAT_ERROR in v0.3.1

[sifmelcara]

When running test with https://github.com/s-yata/marisa-trie/releases/tag/v0.3.1 I get these errors because custom errors like MARISA_FORMAT_ERROR was removed in s-yata/marisa-trie#114

Perhaps the testcases should be update to something like assert "MARISA_FORMAT_ERROR in e.args[0] or "std::runtime_error" in e.args[0]"
