[Bugfix] Fix incorrect completed count of aggregation node for resume run

[Jasmin3q]

Description

Currently we have the bug of returning wrong completed count of aggregation node for resume run. The completed count of aggregation node is 2, but the expected result is 1. That's because the previous aggregation result is also copied to current line_results and counted in the node_run_info.

To exclude the previous result of the aggregation node, we check all the nodes in previous_node_run_infos. If any aggregation node is loaded, we exclude it in _copy_previous_run_result.
