Metrics/ClassLength calls class_definition? on nil.

[reitermarkus]

The Metrics/ClassLength cop somewhere hits a point where it calls nil.class_definition?.

---

Expected behavior

No error.

Actual behavior

Error occurs:

Inspecting 1 file
Scanning /Users/Markus/Downloads/test.rb
An error occurred while Metrics/ClassLength cop was inspecting /Users/Markus/Downloads/test.rb:1:0.
undefined method `class_definition?' for nil:NilClass
/Users/Markus/.config/rbenv/versions/system/lib/ruby/gems/system/gems/rubocop-0.93.0/lib/rubocop/cop/metrics/class_length.rb:48:in `on_casgn'
.
.
.

Steps to reproduce the problem

1. Create a file test.rb with these contents:

A, B, = C

2. Call rubocop test.rb --display-cop-names --debug.

RuboCop version

$ rubocop -V
0.93.0 (using Parser 2.7.2.0, rubocop-ast 0.7.1, running on ruby 2.6.3 universal.x86_64-darwin19)

Is it possible to release as a patch release? It's blocking me on an upgrade to 0.93.
