E3-1596: Fix node graph for new e3 release
The core of the problem is that modules depending on older than newest versions of other modules are removed from the pinned graph. If in turn another module depends on the removed one, attempting to link them causes an exception in JS.
This is the case with displayform
module:
pvxs (older) <- displayform (removed) <- keysight (exception)
