Phys backup while trimming datadir from the file path always added a slash to the trim prefix. In case datadir was set with a tailing slash it led to a double slash and datadir wasn't trimmed at all (Trimprefix("/data/db/file1", "/data/db//")). Therefore in the backup's meta such files contain datadir and the restore would put them in a subdirectory inside datadir, "/data/db/data/db/file1" instead of "/data/db/file1".
This change fixes it.
