Escape patterns script not working correctly

[MaggieCabrera]

While working on https://github.com/WordPress/community-themes/pull/152 I tried to use the escape patterns script and it was failing:

> community-themes@1.0.0 patterns:escape
> node ./theme-utils.mjs escape-patterns

This error seems to happen when you delete or rename a file from the patterns folder without commiting to git. If you change the file contents and run the command, the script seems to work fine.

Steps to reproduce error:

1. Delete or rename a pattern file (for example poetry/index.php)
2. Run npm run patterns:escape

@joanrodas I can avoid the error if I don't rename the file but it still doesn't escape the strings, so the script still needs some debugging apparently. Thanks for your help!
