Rails/SaveBang "check used in conditional" false positive

[jas14]

The Rails/SaveBang cop in v0.74.0 emits a false positive for the "check used in conditional" rule, where the save-like call is actually in the if-body, not the condition.

---

Expected behavior

I expect Rails/SaveBang to suggest I use create! instead of create, like so:

test.rb:1:12: C: Rails/SaveBang: Use create! instead of create if the return value is not checked.
some_model.create if condition
           ^^^^^^

Actual behavior

I get a message about the save-like call being used as a conditional:

test.rb:1:12: C: Rails/SaveBang: create returns a model which is always truthy.
some_model.create if condition
           ^^^^^^

Steps to reproduce the problem

1. Create a file (I named it test.rb) with the following minimum reproducible case code:

some_model.create if condition

2. Execute rubocop test.rb
3. Observe incorrect error message

RuboCop version

$ bundle exec rubocop -V
0.74.0 (using Parser 2.6.3.0, running on ruby 2.6.3 x86_64-darwin18)

FYI this applies to save-like calls in any branch body of a conditional. Examples:

if condition
  model.create
        ^^^^^^
elsif
  model.create
        ^^^^^^
else
  model.create
        ^^^^^^
end
