[#464] Fix double `MorleyLogs` printing

Description

When TestError is UnexpectedInterpreterError _ _ MorleyLogs are printed twice - with Buildable instance of InterpretError and with integrationalTest function from Michelson.Test.Integrational, but they only need to be printed with integrationalTest.

To fix this we need to remove handling of MorleyLogs in Buildable instance of InterpretError.
