Porechop causes workflow to fail if nothing trims from a sample

[Merritt-Brian]

Description of the bug

If a sample doesn't contain any trimmable reads, the file remains the same and the output is not emitted. This makes the pipeline fail. Make the output optional if it fails so the workflow can continue by reverting the next step to use the original fastq file
