msg: don't clear the status line if new and previous status was empty 

This avoids stray newlines when:

1. Some (non-status line) text was output
2. Then an empty status line is output

According to the logic, 2. should print an empty line to show the blank
status line. Don't do that, and instead output nothing in this case.

This caused problems with mpv_identify.sh, and also looked ugly when
using --quiet.
