[PATCH v2] tests: do not use "slave branch" nomenclature

[Paolo Bonzini <pbonzini@redhat.com>]

Git branches have been qualified as topic branches, integration branches,
development branches, feature branches, release branches and so on.
Git has a branch that is the master *for* development, but it is not
the master *of* any "slave branch": Git does not have slave branches,
and has never had, except for a single testcase that claims otherwise. :)

Independent of any future change to the naming of the "master" branch,
removing this sole appearance of the term is a strict improvement: it
avoids divisive language, and talking about "feature branch" clarifies
which developer workflow the test is trying to emulate.
