Improve documentation of Rails::Command.find_by_namespace [skip ci]

Browse source 
* The documentation for `Rails::Command.find_by_namespace` shows an example
with 3 arguments but the method only accepts 2 arguments:
`namespace` and `command_name`.

* For both `namespace` and `namespace:command_name`, a namespace
with the `rails:` prepended is added.

* "rails:commands:webrat" isn't a namespace that can be returned as the
`Rails::Command::Base.namespace` removes the "commands:" part.
