Backport importBatch error check fix

[macterra]

Summary

In importBatch(), the error check and the "already processed" check are in the wrong order. If a batch has both error and imported set, it gets skipped as "already done" rather than recognized as errored.

Current

async function importBatch(item: DiscoveredItem, retry: boolean = false) {
    if (item.imported && item.processed) {
        return;
    }
    if (item.error && !retry) {
        return;
    }

Fix

async function importBatch(item: DiscoveredItem) {
    if (item.error) {
        return;
    }
    if (item.imported && item.processed) {
        return;
    }
