--server-url with trailling slash causes error

[pgagne]

Running rlock like so

 rlock --server-url http://10.0.76.103:8000/  ...

Causes a cryptic error:

{'CONNECTION': 'OK'}
An unexpected error occured!
Traceback (most recent call last):
  File "(redacted)/.venv/lib/python3.10/site-packages/requests/models.py", line 971, in json

During handling of the above exception, another exception occurred:

On the server

Not Found: //api/resource/retrieve_entrypoint/ntdv-3637

However, with out the / it works fine.

This causes issues when you try to copy the url from your browsers or something.
