Unity Dash non-responsive on re-search

[Nathan Williams]

Unity Dash exhibits counter-intuitive behavior when attempting to re-launch a recently launched application.

Steps to replicate:

1) open the Dash
2) type to search for an application, e.g. "term" for terminal
3) hit enter to open the terminal (it defaults to first result)
4) exit terminal
5) re-open the dash, observe that the dash saved the last search phrase, and focus appears to be in the search
6) hit enter without touching the dash to relaunch terminal
7) nothing happens, you have to clear the search box to re-search, or arrow down to actually select the terminal application fromt he returned results

Expected behavior:
1) hitting enter without changing search field content will do the same thing as original search
