Multiple suspected bugs reported by `pylint`

[blackbit42]

pylint is reporting a number issues that more likely than not lead to unhandled exceptions and therefore application aborts if the respective code paths are being hit. I suspect those code paths are for atypical executions, therefore the associated issues have not been spotted so far.

$ pylint pypassport/ | grep "E[[:digit:]]"
pypassport/geojasper.py:32:8: E1120: No value for argument 'name' in unbound method call (no-value-for-parameter)

I am happy to open individual github issues for those problems in case that makes things easier.
