Attempt solution activation following first time patch creation

If the original solution namespace is added to the name of a data source this issue will occur on first time patch creation since the sadl files referenced will not exist.

It is important to avoid adding the solution Y-name (which is a technical name) to the name of any content as this can cause issues such as this during the aliasing process of patch creation
