Summary0002942: Make sym_data_gap regeneration more robust
DescriptionIn some situations where a node has invalid entries in sym_data_gap, it is fair to truncate that table and let SymmetricDS regenerate the entries as needed. It's possible that data_id's in sym_data are out of range from sym_data_event at that point, and also out of range from the default starting data gap (0..50000000).

This change will consider both the maximum data_id in sym_data_event and the minimum data_id in sym_data when generating the new, initial data_gap.

For a concrete example, we saw a situation where the min(data_id) of sym_data was over 79439130, plus there were no entries in sym_data_event in this case. When truncating sym_data_gap in that case, it was regenerated with the default 0..50000000, and was too low to see the actual data in the sym_data table. Manual intervention was required to update the gap to start at the minimum data_id of sym_data.
