Mark ActiveRecord/Aliases as unsafe autocorrect

[prathamesh-sonpatki]

We faced an issue where our custom update_attributes method call was changed to update but the method name remained same in the method definition.

Original code

def update_attributes
end

update_attributes

After running rubocop --safe-auto-correct:

def update_attributes
end

update

So the cop is not safe for auto correct.

Before submitting the PR make sure the following are checked:

• Wrote good commit messages.
• Commit message starts with [Fix #issue-number] (if the related issue exists).
• Feature branch is up-to-date with master (if not - rebase it).
• Squashed related commits together.
• Added tests.
• Added an entry to the Changelog if the new code introduces user-observable changes. See changelog entry format.
• The PR relates to only one subject with a clear title
  and description in grammatically correct, complete sentences.
• Run bundle exec rake default. It executes all tests and RuboCop for itself, and generates the documentation.
