Application Analytics - Flaky cypress fix

[TackAdam]

Description

Application Analytics had three test that were attempting actions before loading was complete if the browser was slow. This was causing flakiness. Adding

cy.get('[data-test-subj="globalLoadingIndicator"]').should('not.exist');

Ensures the actions wait until the elements exist and make the test always pass.
