Fix early hint missing safety margin

Currently only late hints have the safety margin included, due to
inconsistency in the hint-sending methods. This patch makes said
methods consistent. In the future it's worth de-duplicating
said methods but for now this will suffice as a bugfix without
changing the logic or tests.
