Commit Message

Make rescue_from reject meta selectors mixed with exception classes

Previously the `*args` signature meant that:

  rescue_from :all, MyError, with: :handler

silently dropped `MyError`: the `if args.include?(:all)` branch fired
and the trailing argument was never registered. Same for
`:grape_exceptions` and `:internal_grape_exceptions`.

Keep the existing `*args` signature, add a single guard above the
dispatch: if any meta selector is present and `args.size > 1`, raise
`ArgumentError`. Valid forms (`rescue_from :all`,
`rescue_from :all, with:`, `rescue_from MyError, OtherError, with:`)
are unaffected.

CHANGELOG + UPGRADING entries added; three new request_response_spec
examples cover the new ArgumentError contract.
