[Epic] Fix: Pass empty SDL tag properly

[CommandMC]

Wasn't entirely sure how this worked in #1443, didn't test it enough to find this issue

To test, just install Fortnite (or any other game that supports SDL) and see that important files (like the actual executable) are now getting downloaded

I tried this with fortnite and it works

@CommandMC maybe this PR can be done against the main branch instead of beta? in case we do another fix release, so we don't forget to backport this

[CommandMC]

Hm, not quite sure what's up with the checks. Can you skip them somehow?

[Nocccer]

Maybe @flavioislima can trigger them. I can't and manually starting them does not work.

Maybe GH is down again. Try sending a empty commit.

I think it didn't like that I pushed a commit with the exact same message as before

[flavioislima]

I think it is fine to merge now! :D
