When adding an already-added project, "Already Added" dialog is not always shown. [Superlink@Technion]

[JacobKlein]

For the Superlink@Technion project, if I'm already attached to it, and I try to attach to it again, I do not get the "already added" dialog. BOINC should not let me add it again.

Instead, BOINC bypasses the "Already Added" check, and proceeds to this dialog:

---

I believe the dialog
"This project may not have work for your type of computer.  Do you want to add it anyway?"
is preventing the dialog
"You already added this project. Please choose a different project."
from showing first properly.

Fortunately, I don't think there are severe consequences of adding the project again, as I'm not aware of any problems, but...
The UI should not have allowed me to add this project twice.

Further research indicates that the "may not have work for your type of computer" dialog may also be using the selected row as the project to check, even though the user may have pasted a URL.

For instance, if I paste this into the "Project URL" field: ​http://cbl-boinc-server2.cs.technion.ac.il/superlinkattechnion/ while leaving the row on AVC@home, I get the "already added" dialog.

However, if I click the "Spinhenge@home" row, then paste this into the "Project URL" field: ​http://cbl-boinc-server2.cs.technion.ac.il/superlinkattechnion/ , I get the "may not have work for your type of computer" dialog.

Clearly something is not being checked in the right order, and also, if the users pastes a URL, it's still using the select-row as the project to check.  Both of these needs to be fixed.
