[MediaPreview] Calculate media type of content URI by omitting query params

[fluiddot]

I noticed that if URLs passed to MediaViewFragment contain query parameters, it doesn't calculate properly the media type (i.e. if it's an image, a video, or an audio file). This is caused because the isVideo and isAudio don't expect a URL with query parameters. In order to solve this, I updated the logic to extract only the last segment of the URL's path (similar to what we do here).

To test: [TBD]

@fluiddot, is this PR still necessary?

This fix is mainly needed in case we pass query parameters in the video URL, as I explored doing in https://github.com/Automattic/jetpack/pull/30630. However, since we took a different approach I think we can close it.
