You're looking at the wrong thing. The key here is immunity as it is more specific than a spell. Nothing in Heroism says anything about how it interacts with immunity and immunity is silent as well. There is no RAW to interpret on this. There are only personal rulings.Sure there is. You are interpreting the wording of the heroism spell as it interacts with the situation. The spell doesn't say anything about ending an existing frightened condition only that it confers immunity "until the spell ends..." Thus you have to extrapolate and interpret from there - and make the best ruling you can.
