SUMMARY
Configure aqbanking without a customerID crashes KMyMoney. It's most likely an
aqbanking bug (AH_User_SetSelectedTanMethod: Assertion `u' failed).
But KMyMoney should not crash. 

STEPS TO REPRODUCE
1. have a vanilla KMyMoney installation, no ~/.aqbanking folder
2. click settings -> configure aqbanking -> create user
3. select hbci aqbanking
4. setup pin/tan
5. fill in a valid bank code (12030000), bank name (DKB), server url
(https://fints.dkb.de/fints)
6. fill in a valid user name and user id, keep customer id blank!
7. accept certificate
8. fill in a valid pin
9. select a tan method (e.g. chiptan)

OBSERVED RESULT
KMyMoney crashes

EXPECTED RESULT
KMyMoney should give me a reasonable error message if something in the backend
fails.
