Change setupAndWaitUntilReady function to wait until Files app is fully
loaded. This intend to fix flaky tests where tests expect to have Files
app loaded in Downloads folder, however EntryList |updateSubDirectories|
method is being refactored to be asynchronous, which makes Downloads
folder to delay its appearance. This change has had 4 successful runs in
a row in crrev.com/c/1312185 (patchset 2 and 3).

Re-enable test that was flaky on MSAN.
