[inspector] Use 'ServerError' code for application level error

This CL replaces 'InvalidArgument' with 'ServerError' for
Runtime#getExceptionDetails. The reason is that the error we
raise is on the application level, allowing the DevTools frontend
to handle it to a certain degree. 'InvalidArgument' errors would be
interpreted as "something went really wrong", which is not the case
here.
