Run settings can not be changed in master

[impact27]

The run settings can not be changed on the latest master. To reproduce:
1 - Open a new spyder
2 - create a new file
3 - press the run button, a window opens, select command line options, and add "hello"

4 - Press "run" in the window, the following appears in the console as expected: runfile('/Users/quentin/.spyder-py3-dev/untitled0.py', args='hello', wdir='/Users/quentin/.spyder-py3-dev')
5 - press the run button again, this time no args in sight: runfile('/Users/quentin/.spyder-py3-dev/untitled0.py', wdir='/Users/quentin/.spyder-py3-dev')
6 - go to "Open run settings" and see that the settings have been reset. Change back to the settings you want.
7 - Press "Ok" because there is no "Run" this time.
8 - press the run button again, still no args in sight: runfile('/Users/quentin/.spyder-py3-dev/untitled0.py', wdir='/Users/quentin/.spyder-py3-dev')
9 - go back to the run settings, and see that everything has been resetted again
