Alternations don't work with nested paths.

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.

• copy_fieldWithAlternationOfNestedFields
• move_fieldWithAlternationOfFieldInMultipleArraysOfObjects
• move_fieldWithAlternationOfNestedFields
