When continuing an interactive rebase after a merge conflict was solved, if the resolution could not be committed, sequencer_continue() would return early without releasing its todo list, resulting in a memory leak. This plugs this leak by jumping to the end of the function, where the todo list is deallocated.

I found this while adding support of rebase.missingCommitCheck to `git
rebase --continue'.
