remote default with no argument removes default

[kaiogu]

Running dvc remote default with no argument sets default remote to None.
According to documentation this should show the default remote though.

Setting default remote:

>>dvc remote default my_remote
>>git diff
... 
+[core]
+remote = my_remote
...

This should query the default, but sets default to None:

>>dvc remote default
>>git diff
...
+[core]
+remote = None

Hi @kaiogu !

This is definitely a bug on our side. Need to modify https://github.com/iterative/dvc/blob/0.69.0/dvc/command/remote.py#L51 to just logger.info() the existing value.

Thanks for the feedback!
