Fix for https://github.com/aeagle/react-spaces/issues/49

[thekapadia]

Hi @aeagle - our team investigated #49 - and we found it to be a problem when resizable={true} and scrollable={true} - both are enabled.

This change in the Space.tsx file helped fix it. Please review.

@aeagle Any thoughts on this?

Hi @aeagle - did you get a chance to look into this PR?

Hi @thekapadia. My concern with the PR is that it reverses my effort to reduce the markup created by the spaces. The only scenario at the moment where an inner/outer element is required is when a space is resizable and scrollable to properly position the resize handle. At the moment, the change applied by this PR will generate an inner/outer element for all spaces. I am going to see if there is a way to position the resize handle in a scrollable space without requiring the inner/outer element as that would be the ideal solution.

Sure @aeagle, your concern is reasonable.
