Placate exception check validation in sanitizeRemoteFunctionException.

Reviewed by Justin Michaud.

sanitizeRemoteFunctionException() can call JSValue::toWTFString() which may throw under certain
circumstances.  However, it is only called here if exceptionValue.isPrimitive() i.e. it will
never throw.  However, the exception check validator does not know this.  So, we added an
`ASSERT(!scope.exception())` to placate it.

However, if we're forcing exception check validation on a Release build, the ASSERT turns into a
no-op.  The fix is to use EXCEPTION_ASSERT here instead.
