patch 9.0.0993: display errors when adding or removing text property type

Commit: https://github.com/vim/vim/commit/89469d157aea01513bde826b4519dd6b5fbceae4

    patch 9.0.0993: display errors when adding or removing text property type

    Problem:    Display errors when adding or removing text property type.
    Solution:   Perform a full redraw.  Only use text properties for which the
                type is defined. (closes #11655)
