In one configuration, observed errors from LArADC2MeVCondAlg because
low gain data were missing.  With LArADC2MeVTool, this would not be
an error.  Update LArADC2MeVCondAlg so that this is not an error.

A couple JO fragments were referencing the variable geoFlags without
defining it, expecting it to have been set up by another JO fragment.
But in some configurations, this variable now references something
of the wrong type --- another fragment must be clobbering it.

Explicitly import the flags object before using it.
