Interactivity API: Remove redundant server state from Interactivity Router

Remove the workaround for a bug that was fixed in https://github.com/WordPress/gutenberg/pull/66183. Previously, if the store was not initialized with a minimal navigation object, the interactivity-router script module would error.

Props jonsurrell, czapla, gziolo.
Fixes 62465#.
