sensitivityCalculation does not return a clear error message when parameterPath is NULL

[Felixmil]

If parameterPaths is NULL (can happen when you retrieve paths programatically) then sensitivityCalculation() returns an error about missing column (because result dataframe is empty I think).

I think there should be aditionnal check to make sure that the provided parameterPaths argument is not NULL and also that the pkData is not NULL or an empty dataframe.

Thanks to Luis that helped us find out about this.
