--overwrite doesn't overwrite broken symlinks

[dirn]

Paste the command

igir link test --symlink --overwrite --dat=$DAT_PATH/ --input=$BACKUPS/OSCR/ --output=$HOME/ROMs/{es}/

Describe the bug

I had a few bad dumps that were symlinked into my ROMs folder without DAT verification. I deleted the source file, placing the symlinks in a broken state. I redumped the games, placing the new dumps in a different location than the originals. I ran the above command and received errors. The broken symlinks were left behind.

Expected behavior

I expected the broken symlinks to be removed and replaced with ones pointing to the files matched by igir.

Additional context

I only receive the errors for games that have broken symlinks. If I manually remove those, new ones are created. And subsequent runs don't error.
