MultiChainEvent: don't throw in getByProductID

[gpetruc]

The behaviour before this fix causes an exception to be thrown
when using ref.isAvailable() if the product is missing in both
the primary and the secondary file.

This bugfix is already present in 7_3_X and later, see

Please also make a pull request with this change for CMSSW_7_4_X. This will then go into 7_5 since we are still auto-merging those two.

Hi Chris,

The problem is there only in 72X (and possibly earlier).
In new releases it was fixed when thinned collections were introduced.
