Adding `.schema` to S3 prefix has an issue

[nitisht]

Parseable mistakenly adds a / while creating a .schema file or other . files inside the log stream prefix.

I tested for this by tracing on two different MinIo instances.

This is what request looks like on local minio instance

127.0.0.1:9000 [REQUEST s3.PutObject] [2022-08-31T13:16:20.401] 
127.0.0.1:9000 PUT /logstorage/teststream1/.schema?x-id=PutObject
127.0.0.1:9000 Proto: HTTP/1.1

This is request on demo minio instance

minio.parseable.io:9000 [REQUEST s3.PutObject] [2022-08-31T13:23:33.077]
minio.parseable.io:9000 PUT /parseable/teststream1/.schema?x-id=PutObject
minio.parseable.io:9000 Proto: HTTP/1.1
