Minor fixes

@onikisins is the best person to review this.

Yeah sure, it's 3 lines of code anyway ... so it shouldn't require a thorough examination ;)

@heusch , I guess you are aware that builds are failing? Also, would be nice to have unit tests checking if both FrameContainers and numpy arrays are processed properly. Thanks!

added 1 commit

bb659cb3 - [test] added test for helper functions converting array to FrameContainer and vice versa

Compare with previous version

For the builds, yes I am aware of that... But as far as I understand, this has nothing to do with the code I added, maybe @amohammadi could help here.

As for the tests, well ... I added another function, but such cases are already taken care of in your tests. Anyway, tests are failing for another reason anyway (which, again, has nothing to do with what I did)
