"osc service run" fails when using obs_scm and new git filter on the same repo twice

[martinkunkel2]

We sometimes use the obs_scm on the same repo twice and only extract part of the sources.

Minimal example _service file:

<services>
  <service name="obs_scm">
    <param name="url">https://github.com/openSUSE/obs-service-tar_scm.git</param>
    <param name="scm">git</param>
    <param name="revision">master</param>
    <param name="version">_none_</param>
    <param name="subdir">debian</param>
    <param name="filename">debian</param>
  </service>

  <service name="obs_scm">
    <param name="url">https://github.com/openSUSE/obs-service-tar_scm.git</param>
    <param name="scm">git</param>
    <param name="revision">master</param>
    <param name="version">_none_</param>
    <param name="filename">full</param>
  </service>
</services>

This works with revision ed7b12cad10ec7d7c54c4670797db2a61a120822:

$ osc service run

But with latest master revision c58bf82bb0b10420600bb4640c7a6f4963ca6289 it fails:

I assume this is a cause of #397.
Should this kind of service file that I posted above work with the local osc client?
