Fix unit tests by setting botgroup's max_running

[bertinatto]

Addresses #63.

[immerrr]

what are you trying to achieve by setting project's botgroup to each of the testbotgroups sequentially? why do you need many of them?

[bertinatto]

Setting more than one botgroup at once returns a 400 status code. However, many of these botgroups are no longer needed after the last changes.

[immerrr]

i mean running cls.project.settings.apipost(jl={'botgroups': [botgroup]}) for each botgroup is unnecessary, as each subsequent operation overrides the output of the previous one.

Please, have a look. Thanks.

i have. could you please answer the questions in my comment?

[bertinatto]

Done! Thanks.

Sorry, it was a misunderstanding.

@immerrr clarified that recently we ditched the possibility to set multiple botgroups per project. As a result, sequential settings POSTs ¹ won't append new botgroups. In the last push I addressed this.

¹ cls.project.settings.apipost(jl={'botgroups': [botgroup]})
