Fix inconsistent number of load signals and their order

This change tries to match how chromium treats one single load. Before
the pair of loadStarted/loadFinished methods for api classes was called
on delegate's DidStartNavigation/DidFinishNavigation, which might be many
within one single logical load. This is true for multiple usecases (like
multiple redirects on load, immediate form submit on DOM load, page's
subresource load, or just an error page load on failure). Tracking these
methods and deciding when to emit signals based on states are error-prone
and complicates logic for no benefits. Also it somewhat lies about when
real load is done, which is only started and finished on outer methods
DidStartLoading/DidStopLoading, which are conveniently called only once
for all mentioned usecases. So, this change uses these methods to issue
signals for load start/finish, and only makes exception for error page,
which is needed for quick's private test support.
