New cop that detects some logic after render/redirect_to

[fatkodima]

In rails controller, render/redirect_to are not halting the controller's action execution and any logic can be placed after it.
But this looks at least strange/confusing to do so. I recently discovered a case where people used this.

# bad
def action
  # ... logic
  render ...  # <--- not the last statement
  # ... other logic
end

# good
def action
  # ... logic
  # ... other logic
  render ...  # <-- the last statement
end
