    Creates a document's BasicManager and loads it, if we are already based on
    a storage.

    [Note]

    This method has to be called by implementations of <SvPersist::Load()>
    (with its pStor parameter) and by implementations of <SvPersist::InitNew()>
    (with pStor = 0).

    /*  #163556# (DR) - Handling of recursive calls while creating the Basic
        manager.

        It is possible that (while creating the Basic manager) the code that
        imports the Basic storage wants to access the Basic manager again.
        Especially in VBA compatibility mode, there is code that wants to
        access the "VBA Globals" object which is stored as global UNO constant
        in the Basic manager.

        To achieve correct handling of the recursive calls of this function
        from lcl_getBasicManagerForDocument(), the implementation of the
        function BasicManagerRepository::getDocumentBasicManager() has been
        changed to return the Basic manager currently under construction, when
        called repeatedly.

        The variable pImpl->bBasicInitialized will be set to sal_True after
        construction now, to ensure that the recursive call of the function
        lcl_getBasicManagerForDocument() will be routed into this function too.

        Calling BasicManagerHolder::reset() twice is not a big problem, as it
        does not take ownership but stores only the raw pointer. Owner of all
        Basic managers is the global BasicManagerRepository instance.
