Removed unnecessary component tests for doing actions on apply to all panel.
Also figured out why the test was failing. The saved panel dts had to be clicked twice because of focus. thanks @dmlemeshko

LGTM! Bhavya and I had a quick video call and she showed me the use cases under test and her reasoning for removing the individual tests. We're testing the component and its constituent behaviors in EUI, so focusing on the saved query and apply all cases make sense here.
