.toJSON omits commas in object Arrays.

OrientDB Version: 2.2.28

Java Version: 1.8.0_161

OS: windows

Expected behavior

toJSON on embedded properties should export compliant JSON. array of objects should be comma separated.

`[
    {
        "a": "b"
    },
    {
        "c": "d",
        "e": "f"
    },
    {
        "g": {
            "h": "i"
        }
    }
]

should export as is.`

Actual behavior

.toJSON don't insert commas in-between array elements
[{"@type":"d","@version":0,"a":"b"}{"@type":"d","@version":0,"c":"d","e":"f"}{"@type":"d","@version":0,"g":{"h":"i"}}]

Steps to reproduce

insert into testclass content {"testcol":[{"a":"b"},{"c":"d","e":"f"},{"g":{"h":"i"}}]}

select testcol.toJSON()
