Don't bother with Ember.run.once, as we can detect an impending flush
by inspecting the size of the local queue of _deferredTriggers

This should mitigate some costly run-loop pressure.

Inspired to help with: https://github.com/ebryn/backburner.js/issues/51
another quick fix, which should reduce run-loop pressure.
fixed behaviour of store.all() in combination with store.unloadAll() which caused elements to stay in the RecordArray, even if they should have been removed. ref #1611

Remove underscores and rename

Having adapters and serializers with underscores in their names is
causing issues with Ember Appkit's Resolver. The resolver will normalize
the fullpath of the es6 module and calls `Ember.String.dashserize` on
the fullpath. This converts the underscores to dashes, for example:
`-ams` instead of `_ams` so the lookup becomes `app/serializers/-ams`
and this of course cannot be found.

This PR removes what can be argued as an unnecessary attempt to protect
the adapter and serializer names from being overwritten, instead the
convention to be pushed should be to have the names match the
adpter/serializer class name.

In addition, the ActiveModelAdapter's name was strangely called `_ams`
and this does't match the class name at all. There is no 's' in the
class name at all. Instead this PR has opted to rename both the adapter
and the serializer `active-model`.

Data should match the default task as Ember itself

Force underscore after decamelizing typeKey.

Type key is not always camelized, ember-jj-abrams-resolver for example
uses dasherized type keys.
Normalize typeNames when comparing against typeKey.
Don't assume that factory.typeKey is always camelized.
