multiline-if-else: False negatives for android code style

[BraisGabin]

Expected Behavior

Extracted from Android Kotlin style guide

Braces are not required for when branches and if statement bodies which have no else if/else branches and which fit on a single line.
Braces are otherwise required for any if, for, when branch, do, and while statements, even when the body is empty or contains only a single statement.

I can't stand the same for Kotlin coding conventions (but I think that it should apply too). More about this in #812

Observed Behavior

This code is not flagged and it should:

if (true) 50
  .toString()

if (true) 50
else 55

I fixed this issues in a similar rule in detekt detekt/detekt#2835 and detekt/detekt#2051
