[UI] Event tab keeps events from previous pipeline.

[adong]

What happened: The event tab keeps events from the previous pipeline.

See the animated video: https://user-images.githubusercontent.com/15989893/227046233-33f79b7d-dcd0-4635-a1be-e7bd50694a54.mp4

What you expected to happen: Go from pipeline to pipeline should not have the event data preserved in the event tab page

How to reproduce it:

Reproduce steps:

1. Go to https://cd.screwdriver.cd/pipelines/7

2. Search sonar

3. Click the 2nd to the last one, as shown in the screenshot:

4. The event tab shows more events than current pipeline has (by preserving the events from previous visited pipeline)

However, if you go to https://cd.screwdriver.cd/pipelines/777/events directly, you will see it only has fewer events, see screenshot:

It's not just on search, any navigation to a new pipeline doesn't update the events list from previous pipeline
