TrigValTools: don't check file existence when running unit tests

Hello,

As realised in !67637 (merged), trigger tests using RootMergeStep are failing when running unit tests. Currently, in dry_run mode (unit tests), the script looks for files that don't exist and returns an error.

Cheers, Bertrand
