Ensure that bound properties work with {{view}} helper.

Prior to this change, any bound properties specified for components or views would result in the property being set to the actual `Stream` object instead of the property value. Sadly, we had no tests that confirmed this worked so it seemed as if all was well.  We now have tests for this...
I just moved this outside the binding check since we do not need to actually test the RegExp in this case (should be a tad faster).
