ng:view should ignore/abort pending template requests if route changes

[IgorMinar]

scenario:

app with two routes (/a and /b). user navigates to /a and then quckly to /b without waiting for /a to load.

ng:view sends a request to load /a's template and then /b's template. When the responses arrive, both are processed.

we should ignore or better yet abort request generated due to /a route
