IME txn crash problem. It should belong to me, not buster...

I fix it so it now won't crash. It will assert and insert no text if I continue.
I think this may related to rule system RETURN rule.

On Win 10-19-09 bld, crash doesn't occur, but hitting return key twice after JA
text input still wipes out the input.
On Linux 10-19-08 bld, crash doesn't occur under the original scenario, but a
single hit on return wipes out JA text input.
Mac 10-19-08 bld still exhibits the problem of bug 16432.

The problem is we insert 0 character in the nsHTMLEditor . Which later got treat
as end of string in the html rule code.
