Update the logback.xml to log exceptions root cause first

Expected behavior

When an exception is thrown and it has nested causes, the root cause should be the first displayed exception.

Actual behavior

When an exception is thrown and it has nested causes, the root cause is not the first displayed exception.

Steps to reproduce the behavior

Shutting the xsnd or postgres off and leaving the project running show start displaying exceptions.
