[PATCH] rebase-autosquash: add testcase for fixup occuring before its fixed commit.

[PATCH] rebase-autosquash: add testcase for fixup occuring before its fixed commit.

[Yann Dirson]

Can easily occur when one has started splitting a patch in two, and
subsequently wants to migrate more contents from the bottom patch to the
top one: extracting a fixup using an interactive rebase, committing it
between the two.

Currently, the generated instructions do add the "fixup" directive at the
correct place, but the "pick" is also left where it was, making the "fixup"
a noop.
