11178: Fix replace_match_with_if_let removing unsafe blocks r=bugadani a=bugadani
If the assist encounters an unsafe block in one of the match arms, the assist generated intermediate code like the following:
```rust
if let Foo(_) = foo {
<then branch>
} else unsafe { ... }
```
Which was then parsed back and the unsafe branch got completely removed, removing in invalid code output:
```rust
if let Foo(_) = foo {
<then branch>
} else
```
This PR fixes this issue.
However, I'm sure there is a better, more general solution here, but I lack familiarity with rust-analyzer. `make::expr_if` looks like it expects a `BlockExpr` that, when printed, is wrapped in braces correctly, but I'm sure changing the display impl for an `unsafe` `BlockExpr` would have caused problems. I could have changed `make::expr_if` instead to special case unsafe blocks, but that would have meant some expressions getting wrapped by the caller (as previously), and some others by the function.
