[PATCH] t1400: fix --no-create-reflog test and description

From: Kristoffer Haugsbakk <code@khaugsbakk.name>

This test has had the wrong title since it was created.[1] Use `always` like the description says and negate the expected outcome.

The test works since `core.logAllRefUpdates` set to `true` does not create a reflog for that ref namespace. So the test is testing the config variable, not the option.

The test itself is fine and does not hide a bug: `--no-create-reflog` is not supposed to override `core.logAllRefUpdates`.

† 1: 341fb286212 (refs: add option core.logAllRefUpdates = always,
    2017-01-27)

Notes (series):
    From the commit message:
    
      “ The test itself is fine and does not hide a bug:
        `--no-create-reflog` is not supposed to override
    
    A source for that: roundabout through git-branch(1):
    
      “ The negated form --no-create-reflog only overrides an earlier
        --create-reflog, but currently does not negate the setting of
        core.logAllRefUpdates.
    
    I *suppose* that the same applies to update-ref since (I suppose) they
    use the same underlying machinery.
    
    See also git-tag(1) which says the same thing.
    
    update-ref should document the same thing, then.  I have that marked as
    a todo item.  The changes there are a bit too involved to implicate in
    this submission.
