Fixes #6664/BZ1103169: remove incorrect usages of control-width.

The attribute control-width for the directive alch-container-scroll
was being used incorrectly in many cases.  This attribute should be
used for ensuring the element is the full width of the window and is
really only applicable for full width tables.  This commit removes
the incorrect usages of control-width.
