[NUI] Clear old resources cached data

[NUI] Clear old resources cached data

After overhead reducetion patch #5280 merged, Some side effect occured.

Previously we always ask some properties to dali side visual.
But now we return cached value in NUI.

Since URL property clear-up all properties, to fit previous logic,
let we also clean-up cached properties. (Actually, mark only for this case)
