Smarthome: Rule is not executed when no event name is passed

[kubawolanin]

Environment / device: openHAB 2.0 Build #905 / RaspberryPI 3B with openHABian

Steps to reproduce:

1. Create a new rule responding to the event channel, e.g.

rule "Tide Dash button pressed"
when
    Channel "amazondashbutton:dashbutton:Tide:press" triggered
then
    sendNotification("[email protected]", "Amazon button pressed!")
    sendCommand(Vacuum_Dock, ON)
end

or

 rule "Xiaomi Switch"
 when
     Channel "mihome:sensor_switch:<ID>:button" triggered
 then
     var actionName = receivedEvent.getEvent()
     switch(actionName) {
         case "CLICK": {
             <ACTION>
         }
         case "DOUBLE_CLICK": {
             <ACTION>
         }
         case "LONG_CLICK_PRESS": {
             <ACTION>
         }
         case "LONG_CLICK_RELEASE": {
             <ACTION>
         }
     }
 end

1. Try to trigger the events and see the results

Expected result: The rule is triggered and performed actions should be logged in the console.

Actual result: The rule doesn't trigger, nothing is being logged.

Note that both rules worked for me before I updated the distro to the latest one.

When I pass event name to the when section, e.g.

Channel "mihome:sensor_switch:<ID>:button" triggered CLICK

everything works properly as expected.

It looks like #3267 broke it.
@triller-telekom could you please fix it?

[sjsf]

Oh, sorry, it was NOT this PR... My bad!
Thanks for having a look anyway.

[triller-telekom]

Indeed it wasn't my fault. But I fixed it anyway :)
