Roland Haeder 738e22d3eb
Some fixes: 
- Letting $profile_link and $hcard always been overwritten with newly found
  entries has caused DFRN network detectio to fail and "connect" is no longer
  working. This fix makes sure that these both variables are only set if they
  are still empty.
- added more debug lines to see which URL was it before and after webfinger "detection"
