Title: Additional safety regarding network activity indicator.

- Removed a redundant call to -decrementRequests for "single" requests. This
would happen in the url completion block once the request is canceled. This
was causing more calls to -decrementRequests than -incrementRequests.
- The request count is unsigned, so prevent underflow by checking for 0.
- Cancel pending delayed calls to hide the indicator when showing it.
