[FIX]l10n_it_central_journal_reportlab: formatting and partner logic

Fixed grouped formatting (moved values under correct columns, shifted to the right)
Moved content of column "name" under "ref" (as it is the account_move ref)
Inserted in column "name" value of field "name" of first account_move_line
If account type of grouped record of type "asset_receivable" or "liability_payable",
column "name" shows partner name as in original (ungrouped) logic
