Michael Birtwell ad13e2205d Improve exception reports when exception can't be reconstructed
Artiq assumes that all exceptions raised by the kernel can be constructed with
a single string argument. This isn't always the case. Especially for
exceptions that originated in python and were propagated to the kernel over
rpc.

With out this change a mosek solver failure looks like:
```
ERROR    root:logging_tools.py:41 Terminating with exception (TypeError: __init__() missing 1 required positional argument: 'msg')
Traceback (most recent call last):

    python_exn = python_exn_type(

```

With this change we get:
```
