Bug 1452189

Description of problem:
When pushing signed packages into a channel without the "--nosig" option, and adding an unsigned package to the mix, already uploaded packages will be present on the Satellite server, but not assigned to the expected channel.

Version-Release number of selected component (if applicable):
rhnpush-5.5.89-20.el6sat

How reproducible:
always

Steps to Reproduce:
1. Prepare a custom channel on the Satellite server
2. Prepare a few signed rpms, and add an unsigned rpm (one is enough)
3. Run the rhnpush command without the "--nosig" option:

# rhnpush --server=https://satserver.example.com/APP -u admin -p nimda -vvv -c pushchan -d . --newest
Uploading files from directory .
Connecting to https://satserver.example.com/APP

ERROR: /root/rpms/sigmix/rhn-check-1.0.0.1-38.el6.noarch.rpm: unsigned rpm (use --nosig to force)


Actual results:
rhnpush quits on the unsigned rpm (which is expected). Problem is, already uploaded packages are not linked to the channel passed by the "-c" option and end up as packages without a channel. 

Expected results:
Packages already uploaded before rhnpush encounters the unsigned packages and quits should be linked to the correct channel.

Additional info:
This behaviour can be mitigated by using "--tolerant" option, as rhnpush then doesn't quit prematurely, skips unsigned packages, finishes upload of signed packages, and correctly links them to the channel. Still, rhnpush should link all uploaded packages to the correct channel, even if it doesn't upload all of them.
