[Fix #9977] Update Layout/EmptyLineAfterGuardClause to not register an offense if there is another expression following the guard clause on the same line

[dvandersluis]

Layout/EmptyLineAfterGuardClause corrects by adding a blank line after the clause, assuming that it is on its own line (or followed by a comment). However, if there is another statement on the same line, it's not taken into account.

This change does not attempt to correct if the clause is not the last node on the line. It'll leave autocorrection to Style/Semicolon (which currently doesn't do this autocorrection either).

Fixes #9977.
