keepassxc-browser:1.9.1 broke from a undefined "group" property

[wadabum]

Please have a look at keepassxreboot/keepassxc-browser#2262 handling keepassxreboot/keepassxc-browser#2260

Since they seem to have moved the fix to some undated-feature-release, maybe shimming it on the plugins end is worth a quick fix?
(using "folder names" is likely the most "group-ish" - but a empty string will likely do just fine too and be quick to add)

And feel free to toss/ignore/close this if keepassxc-browser:1.9.2 has been released of course :)

KeepassXC-Browser v1.9.1.1 got released that workarounds this issue, but it should still get fixed in KeepassNatMsg.
