Move factories so they are autoloaded

Factories can be defined anywhere, but will be automatically loaded if
they are defined in files at the following locations:
```
test/factories.rb
spec/factories.rb
test/factories/*.rb
spec/factories/*.rb
```
The factories were located in spec/support/ and were not available in
the rails console.
