Delay initial version fetch until there is connectivity (#5603)

* Delay inital version fetch until there is connectivity

* Add test

* Only mock get not whole websession object

* drive delayed fetch off of supervisor connectivity not host

* Fix test to not rely on sleep guessing to track tasks

* Use fixture to remove job throttle temporarily
