Fixes #370.

This PR fixes an incorrect autocorrect for Performance/RedundantMatch when expressions with lower precedence than =~ are used as an argument.


Before submitting the PR make sure the following are checked:

  • The PR relates to only one subject with a clear title and description in grammatically correct, complete sentences.
  • 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).
