Removed an inclusion of t-copy-sub1 in SCSS for Video.

This line was not doing anything and simply causing a warning while
SASS was compiling. The following is the warning:

---
WARNING on line 35 of /home/valera/edx_all/edx-platform/common/static
/xmodule/descriptors/css/_000-5df8e10160f918d31f2b2e8be3ce247d.scss:
".xmodule_edit.xmodule_VideoDescriptor .editor-with-tabs .edit-header
.component-name" failed to @extend ".t-copy-sub1".

  The selector ".t-copy-sub1" was not found.
  Use "@extend .t-copy-sub1 !optional" if the extend should be able to
    fail.
