copy_field of array/repeated field into newly created array of objects/repeated object with $first/$last creates wrong multiple output

[TobiasNx]

Spotted while testing metafacture/metafacture-fix#106: https://github.com/TobiasNx/fix-FunctionalReview-Testing/blob/dfcf4fac13e4deab0606a9131ea846175170cfbc/data/testing/repeatedFieldsArrayToXML

Perhaps this is also a problem for add_field and move_field.
Should be dealt with after: metafacture/metafacture-fix#102

copy_field("animal_string_Array[]", "animals_repeated_SimpleField")
copy_field("animal_object_Array[]", "animals_repeated_ObjectField")
copy_field("animal_object_Array[]", "test_animals_repeated_ObjectField")
copy_field("animal_object_Array[]", "test_animal_object_Array[]")

#This creates trouble - writes into every first object in array
copy_field("animal_string_Array[]", "test_animals_repeated_ObjectField.$first.animalsString_1")
#This creates trouble - writes into every last object in array
copy_field("animal_string_Array[]", "test_animals_repeated_ObjectField.$last.animalsObject_1[]")

#This creates trouble - writes into every first object in array
copy_field("animal_string_Array[]", "test_animal_object_Array[].$first.animalsString_2")
#This creates trouble - writes into every last object in array
copy_field("animal_string_Array[]", "test_animal_object_Array[].$last.animalsObject_2[]")

expected:

{
  "animal_string_Array" : [ "dog", "elefant" ],
  "animal_object_Array" : [ {
    "name" : "dog"

I tested it with and without the underscore in the name, this seems not to be the problem.

Revisit after metafacture/metafacture-fix#102 and metafacture/metafacture-fix#160.

[TobiasNx]

The problem seems to result from the created array not the input arrays.

Integration test:

• copy_fieldArrayOfObjectsAsRepeatedObjectAndThenArrayOfStringsIntoTheArrayOfObjectsWithLastWildcard
