HTTP-Cover fetching isnt working properly with "%d" due to trailing '/' character
By using the configuration "Use HTTP-Cover" with line "http://host/music_dir/%d" the request from M.A.L.P gets resolved to "http://host/music_dir/path%2Fto%2Ffile%2F/cover.png" which is equal to "http://host/music_dir/path/to/file//cover.png". Notice the double '/' at the end. This causes an 404 Error.
In Line 100-102 or in 119 (functions setRegex/resolveRegex) is the "Bug" i think: https://gitlab.com/gateship-one/malp/blob/master/app/src/main/java/org/gateshipone/malp/application/artworkdatabase/network/artprovider/HTTPAlbumImageProvider.java
