Changes to includes aren't triggering a rebuild of parents

[mountainash]

I've noticed that while using -f minify:html,js on lektor server that when a change to an included file is made, the [parents] file isn't getting rebuilt.

When using in a template file:

{% include 

Running `lekor server without the args to trigger the minification plugin allows Lektor to rebuild any files that include the modified file.

I'm running Lektor v3.1.3 with lektor-minify v1.2 on python:3.8 (Docker Compose)

Thanks for opening the issue!

I'm not using Lektor anymore and unfortunately I don't have time to track down the bug. Still, I'd be happy to review a PR fixing the bug!
