After removal of the symlink target file "/usr/lib/jellyfin/bin/jellyfin", file existence check on the symlink "[[ -f /usr/bin/jellyfin ]]" returns false. As a result the symlink is left in place on package purge. The correct check would be "[[ -L /usr/bin/jellyfin ]]", but since it could be a file in cases, e.g. manual fix on file systems with no symlink support or for any other reason, it is easiest to use "rm -f" to assure that it is removed in both cases and not return false even if it does not exist at all.
Additionally this fixes a typo on upstart script check.
