We have to cast to seconds since the Timestamp class always converts it to string for some reason. Why do we do this?

Proto3 JSON represents int64 as strings, and the seconds component of Timestamps is an int64.

I think this would be cleaner if we ran this in two steps:
// If no explicit ordering is specified, use the first inequality to
// define an implicit order.
if (fieldOrders.length === 0) {
for (const fieldFilter of this._queryOptions.fieldFilters) {
if (fieldFilter.isInequalityFilter()) {
fieldOrders.push(new FieldOrder(fieldFilter.field));
break;
}
}
}
const hasDocumentId = !!fieldOrders.find(
fieldOrder => FieldPath.documentId().isEqual(fieldOrder.field));
if (!hasDocumentId) {
...

Fixing a bug in recursive delete where invalid queries would be created on stream errors due to adding two
orderBy('__name__', ASCENDING)clauses when callingstartAfter()(location). The private methodcreateImplicitOrderByadds an implicit orderBy if there is is no documentId on the fieldOrder fields, but we didn't check the case where the documentId comes from the fieldPaths.
