Under what conditions can we get here with an invalid url? Shouldn't this check
be in the call site?

[hashimoto, 2013/12/12 05:55:58]

Among all 4 users of this function:
1. first_run_dialog.cc: Passing a constant URL.
2. browser_commands.cc: Passing a mailto: URL made by the caller. 
3. chrome_shell_window_delegate.cc: Cannot be sure. Too many call sites.
4. external_protocol_handler.cc: Invalid URL should not be passed because
job_factory->IsHandledURL(url) returns true for invalid URLs in
ResourceDispatcherHostImpl::HandleExternalProtocol()

So chrome_shell_window_delegate.cc is the only user who may pass invalid URLs
for this function.
But from what I see from the CL which introduced this check
(http://crrev.com/209751), it seems safe to remove this check.
It should not be dangerous to pass invalid URLs to chrome::Navigate anyways.
