Error when creating a minimal domain

[timfel]

If you use the minimal model from https://github.com/oracle/weblogic-deploy-tooling/blob/master/site/create.md, you get an error currently on these two lines:

weblogic-deploy-tooling/core/src/main/python/wlsdeploy/tool/create/domain_creator.py

Line 490 in 105c9e6

if len(server_assigns) > 0:

and

weblogic-deploy-tooling/core/src/main/python/wlsdeploy/tool/create/domain_creator.py

Line 496 in 105c9e6

if len(dynamic_assigns) > 0:

The reason is that server_assigns and dynamic_assigns are None. A simple fix is this, which does the same thing for objects with a length and works also with None:
