[PATCH 3/4] submodule--helper: fix BUG message in ensure_core_worktree

[Stefan Beller <sbeller@google.com>]

Shortly after f178c13fda (Revert "Merge branch
'sb/submodule-core-worktree'", 2018-09-07), we had another series
that implemented partially the same, ensuring that core.worktree was
set in a checked out submodule, namely 74d4731da1 (submodule--helper:
replace connect-gitdir-workingtree by ensure-core-worktree, 2018-08-13)

As the series 4d6d6ef1fc (Merge branch 'sb/submodule-update-in-c',
2018-09-17) has different goals than the reverted series 7e25437d35
(Merge branch 'sb/submodule-core-worktree', 2018-07-18), I'd wanted to
replay the series on top of it to reach the goal of having `core.worktree`
correctly set when the submodules worktree is present, and unset when the
worktree is not present.

The replay resulted in a strange merge conflict highlighting that
the BUG message was not changed in 74d4731da1 (submodule--helper:
replace connect-gitdir-workingtree by ensure-core-worktree, 2018-08-13).

Fix the error message.
