ZoweExplorerZosmfApi.getSession returning undefined in cases

[JillieBeanSim]

Describe the bug

referenced in PR where sometimes getSession is returning undefined or passed undefined to new VSC Proxy method ProfilesCache.getProfileSessionWithVscProxy. This needs to be investigated and fixed as getSession should always return a zosmf session.

You might be able to use a profile like the one below to replicate the problem.
If you don't have a token stored on that profile, we don't add the tokenType to the session

Thus, we treat it as if it was using basic auth 😋
