Remove one second delay after screen is loaded

This commit removes the one-second delay after a screen loads. Perhaps it was a workaround for an old bug? I verified that it is not necessary, and it was messing up some of my screenshots.

It is possible but unlikely that some users have tests that depend on this delay. The solution is for them to add a `Wait for "1" second` to their steps. It would be better to have this explicitly stated in any case.
