Remove the inx4 index for SQLite2/3 (FilenameId, PathId) on

File table. Replace it by an index over (JobId, PathId, FilenameId).

It is useless for common usage, and causes performance issues.
This index fragments over the time and the update cost grows
very quickly. (This index is not present on Mysql schema)
