Fix suggestion for attempting to define a string with single quotes
Currently attempting to compile `fn main() { let _ = '\\"'; }` will result in the following error message:
```
error: character literal may only contain one codepoint
--> src/main.rs:1:21
|
1 | fn main() { let _ = '\\"'; }
| ^^^^^
|
help: if you meant to write a `str` literal, use double quotes
|
1 | fn main() { let _ = "\\""; }
| ~~~~~
```
The suggestion is invalid as it fails to escape the `"`. This PR fixes the suggestion so that it now reads:
```
help: if you meant to write a `str` literal, use double quotes
|
1 | fn main() { let _ = "\\\""; }
| ~~~~~~
```
The relevant test is also updated to ensure that this does not regress in future.
