[8.x] Fixed DocBlocks

[dunhamjared]

• Replaced @inheritDoc -- missing parent member with doc comments
• Updated docblock for gatherMiddlewareClassNames -- the $middleware parameter can handle arrays and the callLumenControllerWithMiddleware function passes an array

Please always use fully qualified class names in doc blocks.

Mark this as ready when you've converted to FQN, thanks.

Ok, I sifted through the src directory and found a few more doc blocks that needed fully qualified class names.

Also discovered two more @inheritdoc that were missing parent members with doc comments.
