Remove sleep from add_to_space_dialog.ts

[ljelinkova]

I tried to run the tests on the prod preview but ran into issue when on the Create an Application screen the tests filled in the values and clicked Continue button but nothing happened. When I added the small sleep it seems to work.

I initially thought that the problem was that the button was disabled at the moment of clicking but that was not the case. It seems that it is clicked correctly but the action that it is supposed to call is not called. I cannot reproduce it manually.

We should check it on production when the following fix is deployed
openshiftio/openshift.io#3646
