TRestRun wrong members when producing simulation

[jgalan]

At least the Start Date/Time : 1970-1-1 1:00:00 (0) and the Experiment/project : Null seem to have not valid values when producing a file with restG4.

The test was performed with simulations coming from project trexdm-simulations. ${EXPERIMENT} is properly defined and its value is TREXDM.

    <TRestRun name="Background" title="${EXPERIMENT} Simulations. Version ${VERSION}.">
        <parameter name="experiment" value="${EXPERIMENT}"/>
        <parameter name="readOnly" value="false" />
        <parameter name="runNumber" value="${RUN_NUMBER}"/> <!-- Will be set by restG4ToSlurm/ToCondor.py -->
        <parameter name="runDescription" value=""/>
        <parameter name="user" value="${USER}"/>
        <parameter name="verboseLevel" value="1"/>
        <parameter name="overwrite" value="off" />
        <parameter name="outputFileName" value="Run[fRunNumber]_[fRunType]_[fRunTag]_[fRunUser].root" />
    </TRestRun>

It is likely a problem connected with the TRestRun class.
