Fix complete type in nested pattern
Example
---
```rust
struct Foo { num: u32 }
struct Bar(Foo);
fn foo(Bar($0)) {}
```
**Before this PR**:
```rust
struct Foo { num: u32 }
struct Bar(Foo);
fn foo(Bar(Foo { num$1 }: Foo$0)) {}
```
**After this PR**:
```rust
struct Foo { num: u32 }
struct Bar(Foo);
fn foo(Bar(Foo { num$1 }$0)) {}
```
