--------------------------------------
The following paragraphs will detail the origin of the bug.
Firstly, why the need for a state machine in CDVWebViewDelegate? see CB-2389
tel:, telprompt: and maps: url schemes are automatically handled by the system,
and they launch the appropriate system apps. However, this puts our state
machine in an inconsistent state.
The first time the system url scheme is launched, the state machine goes from
STATE_IDLE to STATE_WAITING_FOR_LOAD_START.
The second time the system url scheme is launched, the state machine starts at
STATE_WAITING_FOR_LOAD_START, which leads to the error -- because the first
time, the delegate function webViewDidStartLoad is never called because the URL
was handled by the system (which makes sense).
The true fix is that we apply this patch in Cordova itself -- where we handle
all system URLs by pushing it off to the system first before it gets to the
delegate.
