Adjust integrationtests after #127

[TobiasNx]

Since Fix can create array with $append since #127. I thought we could simplify our integrationtests and delete all set_arrays that are only used to create empty arrays.

As result two integration tests seem to fail now.

1. This seems to be an undetected bug, replace_all now copies an element it should not:

https://github.com/metafacture/metafacture-fix/blob/d18a5035d2b74508d685ec863c91e4382aff2c26/metafix/src/test/resources/org/metafacture/metafix/integration/method/fromXml/toJson/replace_allInOptionalSubfieldOfRepeatedObjectsWithAsterisk/test.fix

I opened a new issue for this: #377

2. https://github.com/metafacture/metafacture-fix/blob/d18a5035d2b74508d685ec863c91e4382aff2c26/metafix/src/test/resources/org/metafacture/metafix/integration/record/fromJson/toJson/copy_fieldToArrayOfStringsWithIndex/test.fix

Catmandu creates new arrays with index numbers.

$ echo '{}' | catmandu convert JSON to YAML --fix 'add_field(list.0.b,test)'
---
list:
- b: test
...

$ echo '{}' | catmandu convert JSON to YAML --fix 'add_field(list.3.b,test)'
---
list:
- ~
- ~
- ~
- b: test
...

I am not sure if I am in favour of this behaviour since this blocks the possibilty of objects with numeric names.

I would prefer to leave the old integration test for method/fromXml/toJson/replace_allInOptionalSubfieldOfRepeatedObjectsWithAsterisk untouched and instead add a new one for #377.

Agree about adding a new test, otherwise +1

[TobiasNx]

Done

[fsteeg]

There's a typo in the path to the new test (Asteris -> Asterisk).

[TobiasNx]

Typo fixed

[blackwinter]

The new test name could reuse the convention from the unit tests (ImplicitArray instead of WithoutCreatingArrayWithSetArray).

I changed a set_array specific integration test, I need to change it back: metafix/src/test/resources/org/metafacture/metafix/integration/record/fromJson/toJson/set_arrayWithoutValuesAndMove_fieldNewArrayOfStringsIntoArrayOfObjects/test.fix
