branch: Fix bug #6356: Reloading image does not work for compiling.

- Add a FileName::refresh function and replace one call to lastModified which was just meant to refresh the file info.

- Refresh the file info, otherwise InsetGraphics::latex might still think that the file does not exist.

see r32354 and r32355.
