No error when combining visibilities after using `ObservationLong`

Currently, I get the following error when trying to combine visibilities:

Please create a unit-test first.

The error is made by changing the parameter number_of_time_steps. However, we need to set this to something else than 1 because of #284.

Could you have a look at it please @rohitcbscient?
