Steps to reproduce:
1) Start eclipse with an environment that has a MINISHIFT_HOME set to one value
2) Create a server adapter with the default minishift home ~/.minishift (ie make no changes)
3) via cmdline, try to setup cdk using cdk 3.2a and the .minishift home folder
4) Try to start the server

Expected results: Server starts as expected
Actual results: No minishift_home is set. The eclipse environment's minishift home is used. The server attempts to start and tells you to call setup-cdk. The user gets very confused, because the server editor clearly is using ~/.minishift as the home.
