Describe the bug

Using the redundant_type_annotation and var isActive: Bool = false doesn't trigger a warning.

Complete output when running SwiftLint, including the stack trace and command used

• Installation method used (Homebrew, CocoaPods, building from source, etc)? Using a pre-built package
• Paste your configuration file:

opt_in_rules:

• Are you using nested configurations? No
  If so, paste their relative paths and respective contents.
• Which Xcode version are you using (check xcodebuild -version)? Xcode 12.0 Build version 12A7209
• Do you have a sample that shows the issue? Run echo "[string here]" | swiftlint lint --no-cache --use-stdin --enable-all-rules
  to quickly test if your example is really demonstrating the issue. If your example is more
  complex, you can use swiftlint lint --path [file here] --no-cache --enable-all-rules.
