fix: prevent vite from crashing where there are no support files or specs found (#17624)

Browse Source 
* fix: no supportfile + no specs, vite don't crash

When there is no values, in the optimization array,
supportFile can be a boolean. the final optimized entry passed to
fast-glog is then `[false]` whic crashes cypress.

This protects against the no-spec issue

closes #17373

* fix: protect startServer from undefined specs
