Uruahiki was intended to be in the movie. The reason why Uruahiki wasn't in the movie, was because of limited run time. You know, how every movie before theatrical release has a chunk of it cut? Same thing happened there. The 2 main reasons why this is being done: Especially the latter. The Boruto with all the scenes kept intact would most likely been clunky to watch, jumping from one scene into another too often.
 * so people don't have to sit in the theater for 3-3,5 hours
 * pacing

The reason why novel adaptation and the recap portion of the manga also don't have the cut stuff, is because they are adaptations of the movie, the released product.

You may say that the anime is the 'uncut' version of events.
