histedit: delete histedit statefile on any exception during abort
When an user aborts a histedit, many things could go wrong. At a minimum, after
a histedit abort failure, their repository should be out of that state. We've
found situations where the user could not exit the histedit state without
manually deleting the histedit state file. This patch ensures that if any
exception happens during an abort, the histedit statefile will be deleted so
that users are out of the histedit state and can at least manually get the repo
back to a workable condition.
