WD: the lack of memory on the disk results in the deletion of the input files

Scenario

1. Open the "Workflow Designer" tab in the UGENE Application Settings.
2. Specify the output workflow folder so that there is no enough space on the disk. The free space should be < 5 GB.
3. Load the attached workflow.
4. Set "R1_cutadapted.fastq.trimmed.fastq" custom file for "Read FASTQ file with reads1".
5. Set "R2_cutadapted.fastq.trimmed.fastq" custom file for "Read FASTQ file with reads2".
6. Set "data/samples/FASTA/human_T1.fa" for "Align Reads with BWA MEM".
7. Run the workflow.
   Expected state:
   After 8-12 min (when free memory runs out) an error occurs:

   Subtask "Filter unpaired reads task" is failed: Writing error

8. Find the input FASTQ files on the disk.
   Expected state: two input FASTQ files are still on the disk.
   Actual state: the FASTQ files were unexpectedly deleted from the disk!
