Fix error using a CSL 0.8 style

Browse source 
transformToDocument() needs a load group, which it takes from the source
document or from the window that created the XSLTProcessor. Neither of
those has existed since 0f2690eb75 in Zotero 8 stopped taking
XSLTProcessor from the hidden window, so the CSL 0.8 → 1.0 upgrade threw
NS_ERROR_FAILURE. In Word, this showed as "Zotero encountered an error
while updating your document."
