patch 8.1.1777: useless checks for job feature in channel test

commit https://github.com/vim/vim/commit/f386f08ccbd88e28479a4131a1b919bd3c0913ea

Date:   Mon Jul 29 23:03:03 2019 +0200

    patch 8.1.1777: useless checks for job feature in channel test

    Problem:    Useless checks for job feature in channel test.
    Solution:   Remove the checks.  Remove ch_log() calls.
