Breaks layout when symlinks are encountered

[kevinvanrijn]

When a symlink is encountered anywhere in the repository the extension fails to calculate the size of that file. When this happens on the top-level of a repository the table breaks as well.

Example:
https://github.com/EIGHTFINITE/jdownloader-portable

Several things to point out:

1. The symlink LICENSE.txt doesn't receive an additional table cell and is missing its size. It should be 48 Bytes.
2. The directory jump Please refer to Other/Source with only a single symlink below it correctly gets the table cell but shows .... It should be 38 Bytes.
3. Navigating into the directory jump shows similar results with the first step showing ... and the second step showing nothing at all.
