[TP-Editor] Adapt content-assist to support of version-ranges/no-version

[HannesWell]

• Remove 'version' attribute from 'unit' proposal
  Now that PDE supports no versions in unit declarations it does not have to be proposed for all cases.

• Skip units with version-range in the 'UpdateUnitVersions' action from the context menu in the Source tab.

Follow-up on #1245.
