only options, no file argument possible - parser errors

[Martin Weis]

calling pastebinit with a file as argument fails: `pastebinit file`

If I understand the command parsing correctly, files as argument were intended:
https://bazaar.launchpad.net/~pastebinit-developers/pastebinit/trunk/view/head:/pastebinit#L338

The traceback below points to a different source location, something fails in the config parser part.

```
Traceback (most recent call last):
  File "/usr/lib/python3.8/configparser.py", line 789, in get
    value = d[option]
  File "/usr/lib/python3.8/collections/__init__.py", line 898, in __getitem__
    return self.__missing__(key) # support subclasses that define __missing__
  File "/usr/lib/python3.8/collections/__init__.py", line 890, in __missing__
    raise KeyError(key)
KeyError: 'page'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/bin/pastebinit", line 366, in <module>
    website, params = getParameters(website, pastebind, content, user,
  File "/usr/bin/pastebinit", line 170, in getParameters
    params[paramname] = paste_config.get('defaults', param)
  File "/usr/lib/python3.8/configparser.py", line 792, in get
    raise NoOptionError(option, section)
configparser.NoOptionError: No option 'page' in section: 'defaults'
```

Found the culprit in my local config file ~/.pastebinit.xml
Restored the default one and now everything works as expected.

Please close this issue and sorry for the noise
close #1914581
