test-serve: make the 'listening at *' lines optional

The daemonized serve process doesn't print these lines out (see 448d0c452140).
I was able to get it to with the following hack:

However, MSYS translates --prefixes starting with '/' to 'C:/MinGW/msys/1.0',
which changes the output.  The output isn't so important that I want to spend a
bunch of time on this, and risk breaking some subtle behavior of `hg serve -d`
with the more complicated code.

    dispatch.dispatch(dispatch.request(['version', '-q'], ui_))
