Problems with Sirius initialization #269

When a representations.aird file is present, there is usually an exception with OML WB 0.9.5.1:

!MESSAGE An internal error occurred during: "Loading models".

The workaround is to delete the representations.aird file, remove the Modeling Perspective from the project and add the Modeling Perspective again. This forces Sirius to create a new representations.aird file; this time, without this exception.
