Docs: Fix link in handlebars text field API

Currently, this link was returning a 404 response. It should be
relative to the /api/classes path. This change fixes the link.
[BUGFIX beta] Correct type of variable initialization

`allowedKeys` should be a string value because it will be passed from template.

Such as:
``` handlebars
<a href="#" {{action "edit" allowedKeys="alt"}}>click me</a>
```

If it is treated as an array, [`allowedKeys.indexOf`][] doesn't work on old IE.
Because `Array#indexOf` is not defined in old IE.

[`allowedKeys.indexOf`]: https://github.com/emberjs/ember.js/blob/a51806a2cdc2fc93f8ed3fe6d0d53ab229c455d3/packages/ember-routing/lib/helpers/action.js#L48

[BUGFIX beta] Add spec for unhandled exception being logged by Test.adapter.exception

The changes in exception handling introduced in
cf0caa04f625067ec3b4629acdec12c8517df94e made a test assertion in an
existing test obsolete, since it wasn't called anymore.

This commit adds a spec for Test.adapter.exception being invoked, when
an exception is not handled.

Correct GH issue URL referenced in blockHelperMissing comments
[BUGFIX beta] {{partial}} helper now works with bound params

{{partial name}} will look up `name` on
the present template context and render the partial
whose name is the present value of `name`. If `name`
changes, the partial gets re-rendered. If name is
falsy, nothing gets rendered. If name refers to a
non-existent template/partial, the same assertion you'd
see if you'd explicitly passed in an invalid template/partial
name in string form will fire.
