[clang-format] Reference qualifiers in member templates causing extra indentation

The following code

```
struct f {
  template <class T>
  void bar() && noexcept {}
};
```

will be formatted to the following with LLVM style, and
`AlwaysBreakTemplateDeclarations: Yes`

```
struct f {
  template <class T>
      void bar() && noexcept {}
};
```

The indentation of the `void bar()` line is wrong.
