swaybar: Make hotspots block bar release bindings

The previous commit prioritized hotspots before bar bindings for press events,
which matches i3's behaviour. However, since hotspots don't need to do any
processing on release events, those were not handled, and simply fell through
to `bindsym --release` bar bindings (if any).

This is counter-intuitive, and doesn't match i3's behaviour. Instead in case
a hotspot handles the press event, it should also handle the release event,
doing nothing, but blocking the event from triggering a --release bar binding.

E.g., in Sway, without this commit, this config. shows a text on tray clicks:

    bar {
        # ...
        bindsym --release button1 exec swaynag -m I_got_the_release_event.
    }

But the same configuration in i3 (with i3-nagbar) doesn't show the text.
