pythonPackages.jira: fix build (#41419)

The build for `pythonPackages.jira` failed with the following error:

```
Download error on https://pypi.python.org/simple/sphinx/: [Errno -2] Name or service not known -- Some packages may not be found!
Couldn't find index page for 'sphinx' (maybe misspelled?)
Download error on https://pypi.python.org/simple/: [Errno -2] Name or service not known -- Some packages may not be found!

    raise DistutilsError(msg)

builder for '/nix/store/8dv7mpspyk6kxwnzqb43rzm4q5j14xp0-python3.6-jira-1.0.15.drv' failed with exit code 1
```

The root issue is most likely caused by some docs fixes upstream
(https://github.com/pycontribs/jira/commit/519183d874fde26e676a75aa53496968643aaac0)
which were released in 1.0.15. The bump (without the fix) has been
performed in 7a6bf668fb73cd4d1096fa1c0162d9c6009f1d7e. Since `sphinx`
isn't needed during runtime, it's not necessary to use it as
`propagatedBuildInput`. In order to work around this the dependency had
to be removed from from `setup.py`.
