convert: check for failed svn import in debugsvnlog and abort cleanly
'hg debugsvnlog' failed with a crash when using the uninitialized transport in
get_log_child if the import of the svn libraries had failed.
'convert' should never get as far as launching 'hg debugsvnlog' if the svn
libraries are missing, but by launching a subprocess there is risk that the
environment is mangled so the second import fails.
It is in principle also possible to launch the command manually.

Are we able to kill the service? if not, the service died on some error
$ kill `cat hg.pid`
