fix for Kitsu and Mal content being still incorrectly requested

[skoruppa]

I noticed that for content id in format

prefix:id:episode

like kitsu or mal, application was still making incorrect requests to addons, for example

LOG  🔍 [isValidContentId] Prefix match result: true for ID 'mal:55825'
LOG  🔍 [getMetaDetails] ID validated: type='series' id='mal:55825'
LOG  🔍 [getMetaDetails] Building URL for addon MAL-Stremio Addon: id='mal' encodedId='mal'
LOG  🔍 [getMetaDetails] Trying addon MAL-Stremio Addon: https://mal-stremio.vercel.app/62402/meta/series/mal.json (id='mal' encodedId='mal' baseUrl='https://mal-stremio.vercel.app/62402' queryParams='none')

with those changes, kitsu and mal are finally treated correctly on both meta and stream screens
