Added assertion for updateLink

Added an assertion for string type. Since you could also pass objects
to `updateLink` (which would always result in false in the next if
statement) containing a link. This PR notifies creators of serializers
so they always use a string when handling links.

Added test for links with type other than string
Removed a duplicate line.
Added test case for push link with null value
Update build command, plus minor text adjustments

a bit verbose, but lets ensure we don’t deoptimize these functions in some runtimes.

* passing arguments object to another function (other then via apply) deoptimizes function body
* materializing the arguments object via splice deoptimizes the function body

Temporary fix for #2344 rollback after delete for recordArrays

This is a temporary fix, it's clear this code needs to be refactored.
Moreover I am not sure that removing deleted records from recordArrays
before they are deleted is a correct design decision.
warn instead of throw when resolving keys to model

Before this commit, if you had a payload like:

```javascript
{
  “posts”: []
}
```

But didn’t have a “post” model defined, Ember
Data would blow up. As discussed in the data
team meeting, we decided to warn if the model
could not be resolved. In this spirit,
Ember Data just doesn’t process what it doesn’t
understand, but can still provide you with a
better debugging message to give you hints on
what your payload should look like.
