rebase -i: remove an unnecessary 'rerere' invocation

Interactive rebase uses 'git cherry-pick' and 'git merge' to replay commits. Both invoke the 'rerere' machinery when they fail due to merge conflicts. Note that all code paths with these two commands also invoke the shell function die_with_patch when the commands fail. Since commit 629716d2 ("rerere: do use multiple variants") the second operation of the rerere machinery can be observed by a duplicated message "Recorded preimage for 'file'". This second operation records the same preimage as the first one and, hence, only wastes cycles. Remove the 'git rerere' invocation from die_with_patch. Shell function die_with_patch can be called after the failure of "git commit", too, which also calls into the rerere machinery, but it does so only after a successful commit to record the resolution. Therefore, it is wrong to call 'git rerere' from die_with_patch after "git commit" fails.
