`with` fails with traceback error on failure `__exit__`

[ikappaki]

Hi,

the with macro fails when an exception is thrown in its body and the __exit__ magic method is hit:

TypeError: 'traceback' object is not callable

1. To reproduce, open up a REPL.
2. Manage a socket connection with and throw anything, it throws an exception about traceback rather than the actual exception

basilisp.user=> (with [sock (socket/socket socket/AF_INET socket/SOCK_STREAM)]
                            (throw (python/ValueError)))
Traceback (most recent call last):
  File "<REPL Input>", line 1, in <module>
ValueError

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "C:\src\basilisp\src\basilisp\cli.py", line 306, in repl
    result = eval_str(lsrc, ctx, ns, eof)
             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "C:\src\basilisp\src\basilisp\cli.py", line 52, in eval_str
    last = compiler.compile_and_exec_form(form, ctx, ns)
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "C:\src\basilisp\src\basilisp\lang\compiler\__init__.py", line 163, in compile_and_exec_form
