"Applying ACL in <room>" and other spoilered room IDs should use pills/aliases where possible

[turt2live]

it's more user friendly to see what room it is. If we can't trick element to spoiler a pill (ie: putting a matrix.to link under the spoiler), include the room ID next to the alias.

For example:

Applying ACL in #room:example.org (!room:example.org)

If there's no alias, fall back to just room ID (as today).
