Luci device tracker: AttributeError: 'list' object has no attribute 'upper'

[Code-TT]

I recently started having problems with the Luci Device Tracker in Home Assistant.
The error occurs regardless of whether openWRT uses SSL or not. Does anyone have any idea what the problem could be?

[LuCI openwrt-23.05 branch (git-24.006.68745-9128656)](https://github.com/openwrt/luci) / [OpenWrt 23.05.2 (r23630-842932a63d)](https://openwrt.org/)

I've just merged PR #61, but I've found that there are some test failures that must be fixed before a new version can be released.

I've just fixed the test case that caused the CI failure and released version 1.1.17.

Close issue.
