Subject: [PATCH] Use a ternary operator instead of relying on AND semantics in
 EditHIstoryDialog

Fixes https://github.com/vector-im/riot-web/issues/11334 (probably).

`allEvents` should never have a boolean in it, so given the stack trace and the code this is my best estimate for what the problem could be. I can't reproduce the problem.
