Remove burstUnusedSeal action

Description

You'll notice that every call to commit(types.ADD_FILE_TO_CHANGED) has a dispatch('burstUnusedSeal'). This implies that there's some broken encapsulation... What if we got rid of the action/mutation burstUnusedSeal and simply updated this property in the relevant mutations (e.g. "ADD_FILE_TO_CHANGED")?

I put together a patch for this (untested):

0001-Remove-burstUnusedSeal-action-for-mutation.patch

Let's handle this in a follow up issue/MR. 😄
