logexchange: convert paths to unix when detecting the active path

This fixes the problem in the tests[1] where Windows was showing the whole path
as the remotename for local repositories.

Somebody with a better understanding of this extension should probably take a
deeper look.  There may be other cases that need to be converted- specifically
the `elif not instance` and the missing `else` cases in activepath().  I also
noticed when adding debug prints that the absolute path is stored in the file,
probably not normalized.  (It's wrapped up in $TESTTMP.)
