`getLabelForValue` returns the wrong format in time scale

[hokolomopo]

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.
