Error on external library scan when adding photos with only numeric descriptions

[jo-gross]

The bug

I sorted and rated many of my photos and wanted to import them as an album, so I can easily view them in my library. However, one of my cameras wrote only numeric values in the description and image description fields. This caused a server error: TypeError: (tags.ImageDescription || tags.Description || "").trim is not a function. As a result, the images were not properly displayed (no thumbnails were generated) and all metadata was missing.

I have already solved this issue in a local dev environment to ensure this is the correct explanation and this is the causing error. A very small PR will follow ;)

Reproduction steps

1. Take an image and add a description to the EXIF Field "ImageDescription" and "Description" (eg. `exiftool -overwrite_original -ImageDescription=1234 -Description=1234 your_picture.jpg`
2. Create an external library, copy the image into that and rescan the library
3. The error should occure, have a look at the logs
