Chained #map methods throw an error.

[wawer77]

When checking map(&:method_x).map(&:method_y) line being a definition of another method, an error is reported:

1 error occurred:
An error occurred while Performance/MapMethodChain cop was inspecting (...)

---

Expected behavior

Inform about the offence / correct the offence.

Actual behavior

I get following message after running rubocop -d:

(x) files inspected, no offenses detected

1 error occurred:
An error occurred while Performance/MapMethodChain cop was inspecting (x)

Steps to reproduce the problem

Define a method with 2 map methods chained, like:

def method
  map(&:method_x).map(&:method_y)
end
