fix(StatusChatListCategory): emit original mouse event data in clicked signal

This fixes a bug that was introduced in 01da750899 with a breaking change
where `StatusChatListCategoryItem`'s `clicked` signal would no longer receive
a `mouse` event object.

The reason this is happening is because we've introduced a new `clicked` signal
on `StatusListItem`. The idea was to rely on that within `StatusChatListCategoryItem`,
however, we didn't take into account that the new `clicked` signal in `StatusListItem`
doesn't emit a `mouse` event object.

To fix this issue could either reintroduce the custom `clicked` handler on
`StatusChatListCategoryItem`, or listen to the original `sensor.onClicked` and
`onTitleClicked` signals exposed by `StatusListItem` instead, ensuring the required
`mouse` event data exists.

Fixes #333
