Describe the bug
webchanges seems to check the root folder, creates and stores config files in the first accessible folder: /data/data/com.termux/shared_prefs/webchanges/jobs.yaml. urlwatch stores it correctly in XDG_CONFIG_HOME:$HOME/.config/urlwatch. $HOME would be /data/data/com.termux/files/home. Migration fails.

To Reproduce
Run webchanges in a non standard prefixed environment.

Expected behavior
Default config files should be stored in $HOME/.config/*.

Version info
Please run webchanges -v and paste the version information as follows (first 3 lines):

• webchanges 3.9.1
• Python 3.10.2
• System Linux-4.14-perf+-aarch64-with-libc(Termux/Android)
