Style/RedundantBegin – false positive when calling a method on the block end

[bquorning]

In v0.93.0, Style/RedundantBegin started taking an offense with this code:

# frozen_string_literal: true

@memo ||= begin
  this
  that
end.foo do
  other_thing
end

---

Expected behavior

No offenses.

Actual behavior

test.rb:3:11: C: Style/RedundantBegin: Redundant begin block detected.
@memo ||= begin
          ^^^^^

Steps to reproduce the problem
