file processing race condition

[JeffreyThiessen]

Describe the bug

Briefly describe the issue you encountered.
When sequencing files are uploaded slowly, sometimes the file processor chain will try to unzip the file before it has been fully uploaded.
This results in a failed FastQC job. FastQC jobs cannot be manually triggered so the user must reupload the file.

Steps to reproduce the problem

What were you doing when you encountered the problem?

1. upload a file very slowly
2. file processor chain starts via SequencingObjectProcessingService
3. gunzip fails due to "corrupt trailer"

Expected behaviour

What did you expect to happen?
SequencingObjectProcessingService.findFilesToProcess should not pick up files that are a part of sequencing runs that are not complete.
