When performing a rebase with --rebase-merges using either a custom
strategy specified with -s or an octopus merge, and at the same time
having gpgsign enabled (either rebase -S or config commit.gpgsign), the
operation would fail on making the merge commit. Instead of "-S%s" with
the key id substituted, only the bare key id would get passed to the
underlying merge command, which tried to interpret it as a ref.

Fix the issue and add test cases as suggested by Johannes Schindelin and
Junio C Hamano.

changed v3 -> v4:
    - added explicit test_unconfig to test case
    - use git config instead of test_config
    - added one more test case

The merge subcommand launched for merges with non-default strategy would
use its own default behaviour to decide how to sign commits, regardless
of what opts->gpg_sign was set to. For example the --no-gpg-sign flag
given to rebase explicitly would get ignored, if commit.gpgsign was set
to true.

Fix the issue and add a test case excercising this behaviour.

Add test cases of various combinations of the commit.gpgsign option and
--gpg-sign, --no-gpg-sign flags with rebase -r with the default merge
strategy. This excercises a different code-path from those with octopus
merges or overridden merge strategy with rebase -s.
