Bug: `RemoveViolationComments` incorrectly modifies whitespace of preceding comments

The `RemoveViolationComments` recipe incorrectly changes the formatting of comments that appear before violation comments when removing them.

### Expected Behavior
```java
int a;  //hello
//violation
int b;
```
Should become:
```java
int a;  //hello
int b;
```
### Actual Behavior
```java
int a;
//hello
int b;
```
The `//hello` comment loses its original whitespace/positioning.
