Use the existing pubkey for the sign in payload

it back in to give to the master for sign in, we can just read the
existing public key file that was just created.

Fix file.managed traceback when source is a list

If file.managed state has a source param which is a list, and none of
the URIs in that list are found, a traceback occurs. This commit
modifies salt.modules.file.source_list to raise an exception when source
is a list and no matches are found, and then catches that exception in
the file.managed state so that Salt can return gracefully with a False
result and meaningful error message.
