Prevent showing the same PDF for different submissions of the same LOI

[andreia-ferreira]

There was an edge case where, after a certain submission, if another one was completed within 1 minute, with the same LOI name, the same PDF report as the previous one would show.

This PR fixes that by appending the unique submissionID to the name of the file so that the same report is no longer re-used, as the file names will be different even if the loiName is the same.
