Inconsistent ifcVersion in IDS testcases about ids

[CBenghi]

Thanks @andyward,
I will have to update the scripts.md file, because IDS files are generated, then accept the PR.

Unfortunately, I still don't have an implementation of verification engine to spot these issues.

My view is that the IFC schema version should be considered.
Indeed I think that wee need a richer regression suite that include such test cases, including pass and fail tests.

A PR is welcome if you can help.

Thanks Claudio. I've put a PR in for these IDS files. It's mainly just to avoid confusion amongst implementors over what the test case is testing.

I've also finally made our xbim IDS verification engine public at https://github.com/xBimTeam/Xbim.IDS.Validator - will update the implementors links via another PR, as this should be a pretty comprehensive & robust IDS 0.97 /1.0 implementation for anyone using Microsoft .NET (including cross platform Core support)
