Change dialog message when there is no protocol to copy
I'm running Tor Browser 6.0a3-hardened on Debian GNU/Linux. When I wanted to Tor Browser, it showed me a message that Tor unexpectedly was closed. I wanted to copy the relevant log messages and clicked on the "copy the Tor protocol message" button (I use the german version which says "Tor-Protokoll in die Zwischenablage kopieren"). After I hit the button a message appeared which read like "Copy ready. 0 Messages were copied" (German: "Kopie vollständig. 0 Tor-Protokollnachrichten sind bereit …").
To me this message doesn't make fully sense. It says that there were 0 messages copied. IMHO it would be better to print something like "Currently there are no log messages to copy." or a similar message to make it clear that there are no log messages.
