"Copy" doesn't work for JSON's array of strings

### Severity

P3 - Medium (Minor functionality affected)

### Which Data Mapper Version are you using?

v2

### Describe the Bug with repro steps

Suppose I have this source

```
{
"field1" : "example",
"field2" : [
"x1",
"x2",
"x3"
]
}
```

and the destination
```
{
"fielddest1" : "example",
"fielddest2" : [
"x1",
"x2",
"x3"
]
}
```

It seems that the "Copy" function of the data mapper doesn't work with a "simple" array of strings (mapping "field2" to "fielddest2")....

### Steps to Reproduce the Bug or Issue

1. create a source and a destination schema that entails an array of strings e.g.
```
"fielddest2": {
"type": "array",
"items": {
"type": "string"
}
},
```
2. try to map the source array to the destination array

This doesn't seem to be supported in the "legacy" data mapper nor the "modern" one.
