[web-nfc] add a cancelAll() instead of cancelPush()

kenchris has just created a new issue for 
https://github.com/w3c/web-nfc:

== add a cancelAll() instead of cancelPush() ==
This would probably suffice for most use-cases as devs can just readd 
the pushes, at least until we get cancellable promises. Also when that
 happens this method still makes sense.
