Bug when there are multiple attachment files

[xenonz95]

When I have multiple attachments whose first attachment is not a PDF file, ZoteroQuickLook will not automatically open the correct pdf file, but will open the first attachment.
This is common in items imported by browser plugins, the first attachment is a web link

I have the same issue when multiple attachments are present. While double click on entry opens the pdf with external application, the plugin fails to show the pdf.
