This ticket is to resolve a TODO in schema/schema_create.c .  When we create a new file in the block manager, we may be operating with a particular file system for the duration of that create call (that is, the file may be created in a cache destined for a bucket).  Meta tracking is used in case there is a failure, the file would need to be removed.  But the current file system is not preserved in meta tracking calls, so we would be removing from the WiredTiger home.  So meta tracking calls should preserve the current file system, and use it when undoing file operations.
