Wrong indent for multiline named arguments

[vRallev]

If this is a duplicate of #918, then please close this issue.

Expected Behavior

This is how Android Studio formats the code. We use 2 space indent, but the result is the same for 4 space indent.

val appStartData = AppStartData(
  appTasks = myProcessInfo.appTasks,
  classLoaderInstantiatedElapsedUptimeMillis =
  Perfs.classLoaderInstantiatedUptimeMillis?.let { it - processStartUptimeMillis },
  applicationInstantiatedElapsedUptimeMillis =
  Perfs.applicationInstantiatedUptimeMillis?.let { it - processStartUptimeMillis }
)

Observed Behavior

KtLint formats the code like that:

val appStartData = AppStartData(
  appTasks = myProcessInfo.appTasks,
  classLoaderInstantiatedElapsedUptimeMillis =
    Perfs.classLoaderInstantiatedUptimeMillis?.let { it - processStartUptimeMillis },
  applicationInstantiatedElapsedUptimeMillis =
    Perfs.applicationInstantiatedUptimeMillis?.let { it - processStartUptimeMillis }
)
