fix conditionals for permissions check

[vpchung]

• Did you run your tests locally?
• Did you add a good description about your changes or additions?

The current issue was that using the set comparison made it so the permissions had to be just READ and DOWNLOAD. If someone had additional permissions, e.g. UPDATE, validation would fail (even though they would technically have access to the project).

Ah interesting, I never thought that people would give the synapse authenticated users group, but I can definitely see how people could give more than download permissions to the admin group.

Thanks!

@vpchung, did you need a patch release?

[vpchung]

No, that was my bad. I was the one who implemented those conditionals haha.

And yes, a patch release would be great, thanks!
