Split the code of the mountindex command to be able to add tests. Fix the way the children of IndexInstanceNode are accessed. Fixes GitLab issue #518. Thanks to TheOneValen @TheOneValen for the report. Remove newlines from the index name levels before using them as FUSE directories. Fixed duplicated FUSE directory removal.
