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

[AbdullinAM]

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()
}
