events files get re-created for existing bold files (batch/incremental mode)

[bpinsard]

Summary

This section of code should be extracted from populate_aggregated_jsons and populate_aggregated_jsons and triggered when converting bold files only (or asl too maybe). https://github.com/nipy/heudiconv/blob/86d22104bc0a6eb4fc488c0f083c52008815b1af/heudiconv/bids.py#L275-L284

problems:

• it recreates template event files for all existing bold, not just the one that were created by the current heudiconv call.
• it is skipped with notop option while it is not "top-level" files .
• ideally it should be able to check for a matching existing top-level events files before creating it.
