alt+f2 & win/super boxes give no feedback if they find nothing to run

[Avi Greenbury]

Binary package hint: unity

If you attempt to run something that's not a command (say, something not yet installed) through the alt+f2 box or the win/super key box, it doesn't tell you that it didn't find anything.

To reproduce:
1. hit alt+f2 or the win key
2. enter some text that's not a command
3. hit enter

Expected behaviour:
1. hit alt+f2 or the win key
2. enter some text that's not a command
3. hit enter
4. have a dialog box or something pop up saying words to the effect of "I couldn't run your nonsense"
