From now on \kern and \mkern remain as ERT as long as the length is invalid.
Fixes #10539 (regression at 10c8d51b).
The only way to produce an InsetMathKern now is via parsing (i.e. file opening
or copy-paste). This is because there has never been any sensible way to input a
valid InsetMathKern, but this is another issue.
