Previous exception ignored in fetchOne of AbstractMySqlGateway

[vlkolak]

Hi all,

Sometimes exception are catched ¹ and never dealt with ².
Coupled with exception nesting or even outright overriden exception ³ it makes development and debugging very complicated.

Could we just set the previous exception, even just the last one, as the previous exception at L107 ?

1. mysql-gateway/src/AbstractMySqlGateway.php

   Lines 98 to 100 in 9cb3297

   	} catch (\Exception $e) {
   	continue;
   	}

2. mysql-gateway/src/AbstractMySqlGateway.php

   Line 107 in 9cb3297

   throw new NoResultException(sprintf('Unable to find an entity of type "%s" for identifier "%s"', $class, $key));
