Error logging filling up disk

Today my OS (vanilla Ubuntu 22.04) warned me that I had only a couple of GB left on my main disk. After some dinging I found that aw-watcher-window was spamming my disk with error logs. For example `~/.cache/activitywatch/log/aw-watcher-window` is currently 160GB.

In those large log files, I see basically every second an entry like this:
```text
2022-12-05 09:17:59 [ERROR]: Exception thrown while trying to get active window (aw_watcher_window.main:110)
Traceback (most recent call last):

BrokenPipeError: [Errno 32] Broken pipe

During handling of the above exception, another exception occurred:
