[BUGFIX] Actually fix subscription_name with periods in it (#861)
Prior PR did not actually work - this actually fixes the bug (#844) where subscription names would drop periods from them, i.e. Mr. Beast would have the name Beast.
POTENTIAL BREAKING CHANGE
If you have a subscription with a period in its name prior to this fix, this change will make it so your download archive is not found since it uses the subscription name in the download archive file path. To fix, simply change the download archive JSON's name to have the actual subscription name, and not the dropped-period one.
