- We used to (re-)load the content on every onStart(),
which is called too when coming back from other actibities.
So if you go home and come back with the task switcher,
all state get reset, including webview zoom/pan and the current tab.
- Introduce a new flag, mLoadWhenResumed, to tell if we really need to
load a message.
Also:
- Start loading a message in onResume() rather than onStart()
to keep it consistent with other fragments.
