[PATCH v6 0/4] "promisor-remote" capability fixes

[Christian Couder <christian.couder@gmail.com>]

This addresses a number of different issues found after the
"promisor-remote" capability patch series was merged.

Changes since v5:

There are only changes in the "t5710-promisor-remote-capability.sh"
test script since v5:

  - Patch 1/4 ("t5710: arrange to delete the client before cloning")
    is new. It moves `test_when_finished "rm -rf client"` before we
    clone. It's a preparatory patch to avoid possible issues in the
    following tests if a clone ever fails in a weird way.

  - In patch 2/4 ("promisor-remote: fix segfault when remote URL is
    missing"), the tests have been improved in a few ways:

      - a `test_when_finished "rm -rf client"` has been moved before a
        clone instruction to avoid possible issues in the following
        tests if the clone fails in a weird way,

      - some instructions to reset `remote.lop.url` on the server to
        it's original value ("file://$(pwd)/lop") have been moved
        before the instructions that unset it or set it to an empty
        value,

      - some `test_when_finished "rm -rf client"` have been added into
        the new tests where the clone is expected to fail, to avoid
        possible issues in the following tests in case the clone
        actually succeeds.
