tests: remove third head in some of the 'rebase-parameters' tests

These tests do not care about that extra branch at all. In future changeset we
will make rebase behave like merge and abort in case of an ambiguous destination
(eg: multiple other heads) and that extra branch will make the command
invocation breaks.

We preventively remove this extra branch from the relevant tests in an
independant changeset to reduce noise and increase confidence in the final
change.
