Datatables accidental reinit on import page buttons

[barbequesauce]

Discovered by @ajslater

Both the flushImports and markImports?action=massimport buttons at the top are asking the datatable to reload, which is not allowed per https://datatables.net/tn/3. Presumably an upgrade-related item that wasn't found until now.

I will forget this if I don't write it down -

script.js, function doAjaxCall line 314:

if ( reload == "table") {
    console.log('refresh'); refreshTable();

function refreshTable line 169:

function refreshTable() {
	var url =  $(location).attr('href');
	$("table.display").load(url + " table.display tbody, table.display thead", function() { 
                         // ^^^ this load is the real problem - but how to fix? 
                         //     reload the page?
		initThisPage();
	});
}

Note this seems to account for both button issues...
