Wrong plural i18n string in Service.cpp

[meskobalazs]

In the keepassxc/src/http/Service.cpp file, there is this line at 548:

tr("Successfully removed %1 encryption-%2 from KeePassX/Http Settings.").arg(count).arg(count ? "keys" : "key")

The string should use plurals correctly, as right now key or keys are hardcoded. I would do the fix myself, but I don't know Qt.

There are more occurrences of problems like this. We need to fix them at some point.

I am no expert on either C++ or Qt, but this should fix it.
