[IA-5074] Improve IA integration test stability

[cahrens]

Jira Ticket: https://broadworkbench.atlassian.net/browse/IA-5074

We are seeing sporadic failures in these tests that indicate that clicking on the name of the newly created notebook failed (the item to click on did exist as no error was thrown, but apparently it was obscured and the click callback did not get triggered). The notebook/analyses is clicked on immediately after the compute modal slides shut, and given that it has an animated transition, I am guessing that is the cause of the problem.

Example failure:

Test: run-rstudio
Status: failed

Failure details: [

Using a delay of 5 seconds passed 4/4 runs. This PR attempts to use a delay that matches the transition animation time, but that may turn out to be flaky given the other operations that are also occurring (spinners in both the side modal and over the page itself).
