gitremote-helpers(1): clarify refspec behaviour

The documentation says that "If no 'refspec' capability is advertised,
there is an implied `refspec *:*`" but this is only the case for the
"import" command.

Since there is a comment in transport-helper.c indicating that this
default is for historical reasons, change the documentation to clarify
that a refspec should always be specified.
