Style/RedundantParentheses should ignore yielding hash literal

[karlwithak]

With a method like:

def foo
  yield ({
    a: 6,
    b: 7,
  })
end

Running rubocop -a autocorrects this to:

def foo
  yield {
    a: 6,
    b: 7,
  }
end

And gives this output:

app/test.rb:4:9: E: Lint/Syntax: unexpected token tLCURLY
(Using Ruby 2.5 parser; configure using TargetRubyVersion parameter, under AllCops)
  yield {
        ^
app/test.rb:4:9: C: [Corrected] Style/RedundantParentheses: Don't use parentheses around a literal.
  yield ({ ...
        ^^

When running this auto-corrected file, I get a syntax error:

app/test.rb:4: syntax error, unexpected '{'
  yield {
        ^

I believe the Style/RedundantParentheses cop should not consider parentheses in this situation to be redundant

I will look into a fix for this
