Host name is not displayed correctly if trigger expression has different hosts.

For example, localhost1 has a trigger below:

{localhost1:trapper.test.last(0)}=0 & {localhost2:trapper.test.last(0)}=0

Then both agent.ping item received 0, information of localhost2 shows "localhost1" as a host name on trigger and events screen. Please see attached screenshots.

It's better to display "localhost2" as a host name on localhost2 screen.
