Fix up mac test client and simple host for remoting.

Fix up mac test client and simple host for remoting.

Remoting's test client and simple host weren't initializing the NSApplication correctly which is required for MessageLoops to work on the Mac. These are just test apps that we use, so I felt it was ok to bring in code from base/test.

Also added a check to message_pump_mac.mm to verify that NSApp is initialized before we attempt to use it.

BUG=NONE
TEST=BUILD

Mark, could you take a look at the message_pump code.

Sergey, could you eyeball the other stuff?
