Complete override not necessary anymore about console-extra-bundle

[seiffert]

Thanks for the input! In fact, I haven't seen this change so far.

I'm not really opinionated about whether all commands should be defined as services. If one does not override Bundle::registerCommands, the commands that don't have dependencies should be registered by the default mechanism. If one of those commands is defined as service as well, it should be re-registered, which shouldn't have any effect (I haven't had the chance to test this, yet). If a command is not defined as a service, it will be registered only once.
This way, everybody's requirements should be fulfilled, right? If so, I will just remove the section where Bundle::registerCommands is overridden from the README. Also, feel free to submit PRs for such small changes ;-)

Well, I wasn't sure, how to handle it, therefore no PR yet :-)

The only thing I could come up with would be optional "dependencies", like setLogger or similar, where you would want to not have the same command registered twice (which afaik would fail).
