Fix for conddb command line tool

[ggovi]

We provide a fix for the conddb tool:
conddb copy --toRun
When the input IOV set starts with timestamp = 0 or timestamp =1 ( both corresponding to 1970-01-01 00:00:00 ) a run matching for the conversion can't be found. This boundary condition is now identified , and an error returned.

Testing: local integration test
