patch 8.1.0702: ":sign place" only uses the current bufferv8.1.0702

Problem:    ":sign place" only uses the current buffer.
Solution:   List signs for all buffers when there is no buffer argument.
            Fix error message for invalid buffer name in sign_place().
            (Yegappan Lakshmanan, closes #3774)
