#1636 MUC: Problem overriding affiliations on room creation from plugin
What steps will reproduce the problem?
Write a plugin that overrides room affiliations from the 'muc-room-pre-create' event.
What is the expected output?
Overriden affiliations should stay overriden.
What do you see instead?
If the hook returns `nil` then another hook adds the sender of the stanza that created the room as owner.
If the hook returns `false` then #1635 is triggered.
What version of the product are you using?
Please provide any additional information below.
Before https://hg.prosody.im/0.11/rev/e488a90195bc the sender of the room-creating stanza was only added as room owner if there were no existing affiliations, but since then this code was unconditional unless the whole event chain is stopped, but see #1635.
