.lock files show up in directory listings

This bug is hard to reproduce timing-wise, but I have received at least one directory listing containing a .lock file.

For reference, this is what it looked like:

@prefix : <#>.
@prefix inbox: <>.
@prefix ldp: <http://www.w3.org/ns/ldp#>.
@prefix terms: <http://purl.org/dc/terms/>.
@prefix XML: <http://www.w3.org/2001/XMLSchema#>.
@prefix dcd: <dcd04010-0722-11eb-aaa1-f5587892eb36.ttl.lock/>.
@prefix st: <http://www.w3.org/ns/posix/stat#>.
@prefix tur: <http://www.w3.org/ns/iana/media-types/text/turtle#>.

Note how it ends with .lock/ as opposed to just .lock, which might be the reason why it is not caught.

Should be fixed when not using on-disk locking anymore (#1475), but wanted to mention this in case there would be issues with other magic extensions.

Issue ではソースファイルやテストは特定されていません。まず、ディレクトリ一覧表示の動作と #1475 で参照されているオンディスクロックの作業を調べ、次に報告されている Turtle の一覧を再現対象として使用してください。一覧に一時的な .lock エントリが表示されなくなり、通常のリソースが引き続き存在していれば完了です。
