Detailed description of the pull request / Additional comments

Serilog has multiple valid logging signatures, but the only one that logs exceptions is if the exception is the first argument. Exceptions can be placed validly as 2nd, 3rd, etc. arguments after a string but those are assumed to be part of the message template and otherwise ignored. This resulted in valid log messages but exceptions that were intended to be logged were not being logged.

• Fixed all Error, Warning, Debug, and Information logging that included an exception at the end of the message and move dit to the front of the message so it would be logged instead of swallowed.
