ProjectManager: Run in Terminal handled incorrect before switching to Run settings

Steps to reproduce:

• create Qt Console Application from template
  • you might want to add some code to have a bit output (cout/cerr/qDebug())
• build & run the application
  • application is started (if output code had been added you'll see it on the Application Output pane)
• switch to Projects view -> Run settings
  • check 'Run in Terminal' (should be checked already, so nothing to do, except verifying that it's checked)
• run the application again
  • qtc_process_stub thingy comes up with pseudo terminal, output (if added) goes there..

Expected:

• if Run in Terminal is checked by default then the terminal thingy should come up always, not only after switching to Run settings
• if it's not checked by default then it shouldn't get checked when first opening the Run settings
