Share links on moved files do not update / work

## Describe the bug
If you share a file, then you move that file, it will still show as shared. The link, however, will not work. The share must be re-made for it to work.

## Steps to reproduce
1. Make a shared file
2. Move the shared file
3. Attempt accessing the file at the first link

## Expected behavior
Either the share to be broken, the share link to re-point to the file, or the share link to show that it is no longer valid.

## Actual behavior
Upon loading the link, the filename is displayed at the top of the screen, but the preview area is blank.
