…g dependency is expected (#479)

In some cases it can be expected that SmartTemplateAnalyzer does not
have access to second-degree dependencies. In such cases, no error
should be thrown. Currently this causes misleading error logs, for
example in case of component preload generation for a Fiori Elements
project where no framework dependencies are available.

Resolves https://github.com/SAP/ui5-builder/issues/404

In addition to #479 the generateLibraryPreload should also ignore missing modules when creating a bundle.
As only files from the workspace are bundled, it's not a problem when dependencies can't be found. Just for self-contained bundles, this is a problem.

See: SAP/ui5-builder#479

Adapt to new Project Graph API (see SAP/ui5-project#457)

BREAKING CHANGE:
* Server now requires a Project Graph instance instead.
* Standard middleware now rely on Project instances being available on Resources (see SAP/ui5-fs#381)
* MiddlewareRepository#addMiddleware has been removed. Custom middleware need to be added to the project graph instead
