Use function-style handler definition in `Connections`
Currently, we get a lot of messages like this:
QML Connections: Implicitly defined onFoo properties in Connections are deprecated. Use this syntax instead: function onFoo(<arguments>) { ... }
Referring to the docs, the correct way of defining handlers in a Connections
object meanwhile is to define a onEvent(params...)
function instead of an "implicit" handler definition. We should convert to this approach to avoid spamming logs with these messages.
