Sync error in log with 0 elements

[jamealg]

Description

This isn't a breaking issue but the error message did throw me off. I have a feed that runs every minute and only includes elements that are newly created or updated. Sometimes there are 0 elements returned. In that case I see this error in my logs:

Most Recent Sync: Starting processing of node #1
↳ Most Recent Sync: Match existing element with data {"blueframeId":""}.
↳ Most Recent Sync: Unable to match an existing element. Have you set a unique identifier for ["blueframeId"]? Make sure you are also mapping this in your feed and it has a value. - Element.php: 126.

There are 0 nodes to process so there shouldn't be a "node #1" to process. The error message doesn't make sense.

It appears to function normally when there are feed items to process.

Steps to reproduce

1. Create a JSON feed that looks like this:

{
"paginationUrl": null,
"broadcasts": []
}

2. Create feed
   Element type: entry
   Import Strategy: Create & Update

3. Run feed via direct feed URL

We just released Feed Me 4.3.0, which clears out all log messages when there are no items to process.
