Suggestion: Check 'videos.results.length' before display in Template

[saulobr88]

Hi,

I'm using ionic-tmdb for my studies and I found this situation:
When clicking on a Movie that doesn't have Trailers (videos on Youtube), the property 'results[0].key' are undefined.

Example: https://api.themoviedb.org/3/movie/414906?api_key=3191a71fe91620589f637340f6a92180&append_to_response=videos

This movie has no trailers yet, so I create this in 'movie-details.ts':
`...

videoResults(movie){

if (movie.videos.results.length > 0){

return true;

}

return false;

}

...`

And put a ngIf in 'movie-details.html':
`...

<ion-row *ngIf="videoResults(movie)">

...`

This works well for me.

Thanks for sharing your project
