[ionicHistory] add method to remove the back view

[ashconnell]

solves issue #3750

Adds a method $ionicHistory.removeBackView() which removes the cached view, element, scope, and rejigs the history. I'm already using this in production in various use-cases.

This predominantly solves the issue where in most angular applications you can use $state.go('app.foo', { location: 'replace' }) except in ionic, the history is managed manually - this is the solution.

Would be good to have it part of the core!

I'm working on the method $ionicHistory.removeFromHistory(stateName/id) which we also need for our app - and the ionic community would also benefit from this going forward. Keep an eye out.

Hi @ashconnell, can you write some unit tests for this? We can't merge this without tests. Thank you for the contribution, this is great!

Thanks,

If I use the ui-router location replace, it doesn't work

 $state.go(toState.name, { location: 'replace' });

but using angular location replace does work:

 $location.path($state.href(toState.name).slice(1)).replace();
