Eliminate `overwrite` hack being used in `convert_input.R`

[Sweetdevil144]

Concerned code line :

pecan/base/db/R/convert_input.R

Line 697 in d4919fa

if (overwrite) {

if (overwrite) {
        # A bit hacky, but need to make sure that all fields are updated to expected
        # values (i.e., what they'd be if convert_input was creating a new record)
        if (exists("existing.input") && nrow(existing.input[[i]]) > 0) {
            db.query(paste0("UPDATE inputs SET name='", basename(dirname(result[[i]]$file[1])),
                                      "' WHERE id=", existing.input[[i]]$id), con)
          
        }
        
        if (exists("existing.dbfile") && nrow(existing.dbfile[[i]]) > 0) {
            db.query(paste0("UPDATE dbfiles SET file_path='", dirname(result[[i]]$file[1]),
                                      "', ", "file_name='", result[[i]]$dbfile.name[1], 
                                      "' WHERE id=", existing.dbfile[[i]]$id), con)
          
        }
      }

Any more info about usage of this piece of code, maybe how do we eliminate these hacks within convert_input ?

Will reference those changes in #3338 once all concepts are clear.
