[PATCH 2/3] t3418: decouple test cases from a previous `rebase -p` test case

["Johannes Schindelin via GitGitGadget" <gitgitgadget@gmail.com>]

From: Johannes Schindelin <johannes.schindelin@gmx.de>

It is in general a good idea for regression test cases to be as
independent of each other as possible (with the one exception of an
initial `setup` test case, which is only a test case in Git's test suite
because it does not have a notion of a fixture or setup).

This patch addresses one particular instance of this principle being
violated: a few test cases in t3418-rebase-continue.sh depend on a side
effect of a test case that verifies a specific `rebase -p` behavior. The
later test cases should, however, still succeed even if the `rebase -p`
test case is skipped.
