As list of actions available grows the same code is replicated for
each action execution method. This CL adds a couple helper methods:
ExtractFrameAndVerifyElement
SimulateKeyPressWrapper
To encapsulate some logic in one place.

Add CloseTab and PressSpace actions to captured sites framework

Fixed multiple tests by adding additional methods and reviewing the
stored site recipe files.
