Bug: inconsistent JSON outputs

[dgarijo]

When doing rsef assess -i https://doi.org/10.1098/rsif.2022.0412 -U -B I get:

{
    "RSEF Output": [
        {
            "title": "Learning anisotropic interaction rules from individual trajectories in a heterogeneous cellular population",
            "implementation_urls": [
                {

When doing rsef assess -i json_test.json -o out_test.csv -U -B I get:

[
    {
        "title": "WIDOCO: a wizard for documenting ontologies",
        "implementation_urls": [
            {

This is inconstistent
