public const CROSSREF_API_URL = 'https://test.crossref.org/v2/deposits';

Hi ajnyga,
Thank you for updating Crossref plugin for OMP 3.4
I noticed that, in CrossrefExportPlugin.php line 39;
public const CROSSREF_API_URL = 'https://test.crossref.org/v2/deposits';
it points to test api.
So, on the Crossref live server, I get the "unrecognized publisher prefix" error.
I can successfuly deposit doi when I change this line to
public const CROSSREF_API_URL = 'https://api.crossref.org/v2/deposits';
Since I'm not a programmer, I only made this correction by looking at the old (3.3) version. If it's correct, I wanted to let you know if you can fix it too. Best regards,
