Add support for JIRA custom fields that don't have default values

[tmyllymaki]

As I'm creating an issue to Jira the "add a " part of UI is empty and I can't open the issue type list:

Tested in VSCode and Rider.

Hi @tmyllymaki currently codestream is limited in the following way: we can only create issues that either don't have required custom fields, or if they do have required custom fields, there is a default value.

Is it possible that for your project, all of the ticket types contain a required custom field that does not have a default value?

[tmyllymaki]

I guess it's a plugin field which is required. It assigns a default value but I'm not quite sure if it has a proper default value. Couldn't figure anything else. Other required fields were regular Summary etc.
