Bug 30196: Odd number of elements warning caused by dt_from_string

Koha/DateUtils' dt_from_string is a sub expected to return a scalar, but
does not in all case.

In one instance, tt simply return... nothing, which cause one common call
output_pref( { dt => dt_from_string( $serinfo->{$d} ), dateonly => 1 } );
to output a warning.

Simply returning undef instead will solve the issue.
