Add -r to the xargs. This should prevent xargs from running the tar if there isn't anything on the input.
However, you really need to reconsider using tar with xargs. If the filename arguments are long enough to cause xargs to run a second tar command you'll overwrite the first and it will appear that you only got the last n files in your archive.
Try this in a directory with a few files and see what happens:
The output from the -v will indicate that all files were passed to tar, but the table of contents will show only one file. (-L causes xargs to use at most one input line per invocation simulating what it would do if it needed to invoke multiple instances of tar)
