AutoComplete.bash generates duplicate function names for same paramLabel

[btw04]

This issue is similar to #2498. For a command that has two options with the same paramLabel:

    public enum ECategory {
        ALL,
        INFO,
        DEBUG
    }

    @Option(names = "--debug", paramLabel = "CATEGORY")
    ECategory debugCategory;

    @Option(names = "--trace", paramLabel = "CATEGORY")
    ECategory traceCategory;

The generated auto complete script generates two functions for the options, but uses the paramLabel as a function name for both, resulting in a duplicate function name.

  local CATEGORY_option_args=("ALL" "INFO", "DEBUG") # --debug values
  local CATEGORY_option_args=("ALL" "INFO", "DEBUG") # --trace values
