    Stop duplicate entries for the invoice taxtable cell
    
    When the ledger is loaded, the list for the taxtable combo is created
    but as the item_list gui is not initialised yet a temporary list store
    is used. This is done twice and hence end up with duplicate entries. To
    fix this add the missing gtk_list_store_clear to
    gnc_combo_cell_clear_menu to clear the temporary list store when the
    item_list is not initialised.

    Test for Invoices XML dates not being INT64_MAX
    
    To prevent errors being logged to the trace file when invoices are
    saved test for the date values not being INT64_MAX which is an unset
    date.

    Prevent artefacts of imported transactions from showing
    
    When you start the import process, possible imported transactions are
    displayed in the source open register and if you deselect any and press
    the OK button you are left with blank lines in the register for those
    deselected so move the gnc_gen_trans_list_delete to before the gui
    refresh call.
