Remove sleep from create space and create application

[ljelinkova]

I had to add browser.sleep before entering values for space and application name otherwise only first few letters were entered (like e2e- instead of the full name).

I suspect this is due to the new modal window and could be resolved by waiting until the text field is focused. However, that does not work at the moment.
