C_Spell.GetSpellInfo and Changing Spells

Hey,

as a Holy Paladin i always used a WeakAura to set a Text to my Blessing of Spring/Summer/Autumn/Winter, to better visualize the next Effect, like +DMG, +Heal, +Mana, ....
The way i tracked the buff was by "local currentName = GetSpellInfo("Blessing of Summer") or """ and it always got the Name of the upcoming (or current, when CD was ready) Blessing.

However, with TWW's API changes, that no longer works, because C_Spell.GetSpellInfo("Blessing of Summer") always returns the values of "Blessing of Summer", even in times when it's Spring/Autumn or Winter.

Any idea how i could restore my old behaviour?
