[Clangd] Ensure children are always RootStmt in ExtractFunction (Fixes #153)
Summary:
We weren't always checking if children are RootStmts in ExtractFunction.
For `void f([[int a]]);`, the ParmVarDecl appeared as a RootStmt since
we didn't perform the check and ended up being casted to a (null) Stmt.
