Fixes #8871.

This PR fixes a false positive for Style/RedundantBegin when using begin for method argument or part of conditions.

begin keyword may be redundant when using only one expression in begin of each issue case.
However, since it is the unintended case for #8822, I think it can be implemented as an enhancement different from this bug fix.


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.

Fixes rubocop#8871.

This PR fixes a false positive for `Style/RedundantBegin`
when using `begin` for method argument or part of conditions.

`begin` keyword may be redundant when using only one expression
in `begin` of each issue case.
However, since it is the unintended case for rubocop#8822, I think it
can be implemented as an enhancement different from this bug fix.
