Conditional `any_equal` not working correctly with path wildcards.

[blackwinter]

When using path wildcards (#89) to select multiple subfields, any_equal fails to match any of them (see 8777ffd for unit tests, and Limetrans for a real-world use case).

Also, there's a case to be made that alternations don't work as intended: data.name|data.nome will be split into data, name|data and nome instead of data.name and data.nome. Which is why the nested tests don't fail.

Seems to be the same underlying cause as #119: IllegalStateException: expected String, got Array (when requiring value to be a string instead of converting it to a string: asString() vs. toString()).
