Fix tests incompatible with latest WebSocket spec.

[Issue#]   265
[Problem]  Failing TCT tests.
[Cause]    The tests call WebSocket.close() and expect to get an
           onmessage event after the call and before the
           connection is closed. This can not happen according to
           the WebSocket spec.

           There are two important points:

           The first point is what WebSocket.close() is supposed
           to do:
           http://www.w3.org/TR/websockets/#dom-websocket-close

           3. -> Otherwise section applies in all tests:
           "Set the readyState attribute's value to CLOSING"

           The other point is what happens when readyState is
           not OPEN:

           http://www.w3.org/TR/websockets/#feedback-from-the-protocol

           "When a WebSocket message has been received ... follow
            these steps:

           1. If the readyState attribute's value is not OPEN, then
              abort these steps."

           Chromium aborts at step one, preventing any further
           onmessage events. The event handler would be called in
           step 5.

           All these tests call WebSocket.close() before the onmessage
           event is received, preventing the event to be delivered.

[Solution] Move the call to WebSocket.close() to the end of the
           onmessage event handler.

[Indexeddb] Changed attribute name from multientry to multiEntry

According to the deprecated standard, IndexedDB's Index object should
have attribute named "multientry". The latest standard says that
this attribute should be named "multiEntry" (e is uppercase).
