An empty dictionary database reports null entries instead of [] in the JSON output.

"dictionaries": [
                {
                        "path": "./gboard-data-10.2.07.351353117-release-arm64-v8a/data/data/com.google.android.inputmethod.latin/databases/PersonalDictionary.db",
                        "entries": null
                }
        ],
