"Open in Terminal" does not open the selected directory

[David Hedlund]

#### Expected behaviour
* The selected directory in caja should be opened in File -> "Open in Terminal" (in this case ~/.config/, not ~/.config/)

#### Actual behaviour
* ~/.config/caja/ will be opened in the terminal, not ~/.config/

#### Steps to reproduce the behaviour
* In caja, open a sub-directory in caja, for example ~/.config/caja
* Go back one directory level, in this case to ~/.config/
* Open File -> "Open in Terminal"
