Fix: Avoid serializing dangerous types.

[lucas-zimerman]

This will stop the drop of events and transactions if their content contains a dangerous class type and junk to be serialized.

Changes

• Replaced property values by null if the type is

Exception
Type

• Replaced property value by null if the namespace belongs to System.Reflection (avoiding types that leads to infinite loops by self including themselves).

Close #1108, partially close #962.
EIDT: Might also close #950 because it's one of the type of issues that got fixed by removing references to System.Reflection (I wasn't able to reproduce it with TimeZone)
