Apparently you cannot cast ignite during a Guardian Angel resurrection in a normal game. You can only do it in practice tool with auto-refresh cooldowns. GA places summoner spells on a 4 second cooldown (resurrection happens over 4 seconds) and does not actually disable them, allowing the auto-refresh to reset them.
