`getLabelForValue` returns the wrong format in time scale

### Expected behavior

Calling `timeScale.getLabelForValue(value)` should return a value formatted with the format in `options.displayFormats` for the current time unit.

### Current behavior

Calling `timeScale.getLabelForValue(value)` returns a value in the `datetime` format, instead of the format defined in `options.displayFormats` for the current time unit.
