change to assert-dynamic-error

Input string (9 characters)

1+2+3*4+5

Illustrates the way to handle dynamic errors in a test: use assert-dynamic-error.

It's not formally a grammar error, since this grammar will work fine for some inputs and processors are not required to reject the grammar. So assert-not-a-grammar is not the right thing.

It's not formally a failure to parse the input, since this input string is perfectly grammatical against this input grammar. So assert-not-a-sentence is not the right thing.

The error arises in serialization and only at run time. So assert-dynamic-error.

Expected result

Raises a dynamic error: one of D01, D02.
