Inner Exceptions of AggregationException are not logged

[ludekcakl]

Expected behavior

If test fails with AggregationException than all inner exception stack traces should be part of ExecutionResult.StackTrace

Actual behavior

Only Message and StackTrace from AggregationException is in the result.

Steps to reproduce

1. Create test which throws AggregationException containing one or more inner Exceptions
2. Run the test

Gauge version

0.5.3

Proposed solution

SandBox.cs:70

executionResult.StackTrace =  innerException is AggregationException 
? innerException.ToString() 
: innerException.StackTrace
