merge-recursive: avoid directory rename detection in recursive case
Ever since commit 8c8e5bd6eb33 ("merge-recursive: switch directory rename detection default", 2019-04-05), the default handling with directory rename detection was to report a conflict and leave unstaged entries in the index. However, when creating a virtual merge base in the recursive case, we absolutely need a tree, and the only way a tree can be written is if we have no unstaged entries -- otherwise we hit a BUG(). There are a few fixes possible here which at least fix the BUG(), but none of them seem optimal for other reasons; see the comments with the new testcase 13e in t6043 for details (which testcase triggered a BUG() prior to this patch). As such, just opt for a very conservative and simple choice that is still relatively reasonable: have the recursive case treat 'conflict' as 'false' for opt->detect_directory_renames.
