 Description   

In the classic engine the ExprMatchExpression has a special logic to tolerate DBExceptions when ExprMatchExpressionMatchesReturnsFalseOnException failpoint is on. 

This failpoint is used by the fuzzer to mitigate false-positives failures as described here.

There is no similar logic implemented in SBE, and as a result it causes certain queries to fail in the aggregation fuzzer.

The issues was revealed while investigating this fuzzer failure.
