After the expectation was marked as [Pass Timeout] previously, a flaky failure started showing up in the result dashboard.

Noticed that there is a test expectation set as [ DumpJSConsoleLogInStdErr ] in LayoutTests/TestExpectations. 

Will update the test expectations in ios-wk2 to [ DumpJSConsoleLogInStdErr Slow ] to stop the failures. This will also determine if the timeouts are actual timeouts, or a test just being slow.
