Correctly handle indent for if/when conditions with line comments before them

Currently, line comments break the indent for all expressions with conditions (i.e. everything that uses `emitKeywordWithCondition). Line breaks force a new line, however because no actual GJF `breakOp` was called, it is not aware of the break and does not add necessary indents:
```
if (//foo
x) {
bar()
}

when (//foo
x) {
1 if //foo
baz() -> TODO()
}

```
