Change behaviour of standardLocals in blueprints for slashes

This PR strips the slash from some of the standard locals in blueprints.

An example of before and after with the command `ember generate view foo-bar/baz-qux`:

Variable | Before | After
-----------|----------|---------
`dasherizedModuleName` | `foo-bar/baz-qux` | `foo-bar/baz-qux`
`classifiedModuleName` | `FooBar/bazQux` | `FooBarBazQux`
`camelizedModuleName` | `fooBar/bazQux` | `fooBarBazQuix`

`dasherizedModuleName` is left alone, as that is used for the generation of the files themselves.
See the new tests for details on how this affects all the different included generators. (It is most obvious in the generated tests).

`classifiedPackageName` should probably also be changed, but I don't know any usecases for it right now.
