don't pass puppi NaNs to pseudojet methods

[slava77]

fix crash reported in https://hypernews.cern.ch/HyperNews/CMS/get/recoDevelopment/1385.html
[and likely similar ones observed with the previous versions in 0T in the past]

tested in CMSSW_7_4_12 with the setup reported in the HN:

• crash was reproduced (faster with a skip of 2500 events) in the original release
• crash is gone with the fix (the pt=0 and y=99 didn't reappear as an issue downstream)
