Add a test case ProcessAPITestCase.test_remote_launch() which tests SBProcess.RemoteLaunch()

API with a process not in eStateConnected, and checks that the remote launch failed.

Modify SBProcess::RemoteLaunch()/RemoteAttachToProcessWithID()'s log statements to fix a
crasher when logging is turned on.
