[81X] Temporary fix for multi-IOV input in MillePede

[ghellwig]

Adds a protection against multi-IOV input for MillePede to prevent issues like reported in the Tracker Alignment HN.

This is meant to be a temporary fix to quickly protect against this problem. The mid-term solution which is in preparation will properly handle multi-IOV input instead of prohibiting them.

This pull request is fully signed and it will be integrated in one of the next CMSSW_8_1_X IBs (tests are also fine). This pull request requires discussion in the ORP meeting before it's merged. @slava77, @davidlange6, @smuzaffar
