Metrics/AbcSize with auto-gen-only-exclude option

[jpawlyn]

When comparing the .rubocop_todo.yml file generated with:

rubocop --auto-gen-config --auto-gen-only-exclude --no-exclude-limit

versus

rubocop --auto-gen-config --auto-gen-only-exclude --exclude-limit=100000

the exclude section for Metrics/AbcSize is absent with the former and a Max value is given instead.

---

Expected behavior

I would expect the two versions of .rubocop_todo.yml to be the same since the number of excluded files for Metrics/AbcSize is only 52.

Actual behavior

Using the --no-exclude-limit option gives:

# Offense count: 69
# Configuration parameters: AllowedMethods, AllowedPatterns, CountRepeatedAttributes.
Metrics/AbcSize:
  Max: 43

Steps to reproduce the problem

The problem only occurred when the offense count was 25 or above but it could be the number of excluded files is also a factor.
