Not allow to pass an empty actions to viewset.as_view()

[BrickXu]

Validate actions value when invoke as_view(), raise a TypeError if no actions was passed in.

Refs #2171

Also add unittest for viewset.as_view()

METHOD is a confusing string to use here, as it could mean the request method. ACTION would be more descriptive.

[BrickXu]

OK.

Not sure, but I was following the documentation about testing and got this exception

The actions argument must be provided when calling .as_view() on a ViewSet. For example .as_view({'get': 'list'})

So, should the documentation be updated to add this actions argument?

AccountDetail isn't a viewset so it doesn't have any use of the actions

Ah yeah, of course, sometimes all the different kind of views are confusing ;)
