Revert revision 14819 and my faulty fix for it.
* src/mathed/InsetMathScript.C
(InsetMathScript::write): Do not add braces to the nucleus
* src/mathed/MathParser.C
(Parser::parse1): Do not remove brace insets from the nucleus of
script insets
* src/mathed/InsetMathNest.C
(InsetMathNest::script): ditto

Handle properly script insets which nucleus has more than one
element (like {a'}^{2}). (froward port from 14802)
* src/mathed/math_nestinset.C (script): when creating a script
inset, handle specially previous atom if it is a MathBraceInset
(this is used in interactive input).
* src/mathed/math_parser.C (parse1): when creating a script inset,
handle specially previous atom if it is a MathBraceInset (this is
used in parsing phase).
* src/mathed/math_scriptinset.C (write): put nucleus into braces
if it contains more than one element or is itself a script inset.
