Layout/SpaceAroundEqualsInParameterDefault only registered once in a line

[rdunlop]

If a single line of code has multiple offenses for the SpaceAroundEqualsInParameterDefault cop, only the first one is detected (in certain situations).

This appears to have been first reported by @jsmestad in #8514 (comment)

Reproduction scenario:

class Test

  def log_msg(msg, level =:info, olevel=:error); end

end

Expected output:

Offenses:

spec/models/test.rb:3:25: C: Layout/SpaceAroundEqualsInParameterDefault: Surrounding space missing in default value assignment.
  def log_msg(msg, level =:info, olevel=:error); end
                        ^^
spec/models/test.rb:3:39: C: Layout/SpaceAroundEqualsInParameterDefault: Surrounding space missing in default value assignment.
  def log_msg(msg, level=:info, olevel=:error); end
                                      ^

1 file inspected, 2 offenses detected, 2 offenses auto-correctable

Actual output:

Offenses:

spec/models/test.rb:3:25: C: Layout/SpaceAroundEqualsInParameterDefault: Surrounding space missing in default value assignment.
  def log_msg(msg, level =:info, olevel=:error); end
                        ^^
