Exceptions only being saved once on logs table after version 1.0.70

Hi, I'm using a mechanism for retrying failed activities via signals similar to the one suggested in this previous discussion and after updating from version 1.0.69 to 1.0.70 I noticed that exceptions were not being saved on workflow_logs on each "retry" anymore, and even when different exceptions happen in different activities they are never logged in the workflow_logs table after one exception is logged previously during the workflow lifecycle, is this a bug or is it the correct way exceptions should be logged ?

I believe this new behavior is linked with changes to the Exception class in Pull Request #348.

This was a bug. The suppression of duplicate exception messages was too broad. PR #375 will fix this.
