[BUGFIX beta] The router should cleanup itself upon destroy.

Prior to this change the router did not cleanup its location object upon
destroy. This caused multiple transitions to be triggered after an
`App.reset()` call.

Resolves #3669.

[BUGFIX beta] Remove import statement of Router

Since the router.js sync in cf0caa04f625067ec3b4629acdec12c8517df94e,
a `TransitionAborted` rejection is handled by the router (see
http://git.io/Sf38aQ) so there is no need to re-check for this in
the Ember.Test.adapter#exception handler.

[BUGFIX beta]  sort guid fallback unconfused by ObjectProxy.

`Em.computed.sort` uses a guid check as a fallback comparator.  In order to
search for items correctly, it also wraps items on removal in an object proxy to
shadow new values with the previous values.

This proxy needs to be sort-equal to the actual object.  To ensure the guid
fallback check treated the item and the proxy as equal, it had a check
`ObjectProxy.detectInstance`.  This check is obviously deficient in the face of
items that might themselves be `ObjectProxy`s, such as `ObjectController`s when
using `@this` as the base array in an `ArrayController`.

This commit creates a local type of `ObjectProxy`, `SearchProxy`, to avoid this
confusion.

Fix #3720.
[BUGFIX beta] Added assert mismatched template compiler version.

See #3728. Using an old version of Ember to precompile templates
can result in an unusual error when trying to render a component
in block form, e.g.

```
  {{#my-component}}Hello{{/my-component}}
```

This commit adds an assert to give the user more information
as to what's going on.
