repeat explorer redirects to /galaxy/galaxy which does not exist

[martenson]

when accessing https://repeatexplorer-elixir.cerit-sc.cz/galaxy/

you'll get redirected to https://repeatexplorer-elixir.cerit-sc.cz/galaxy/login/start?redirect=%2Fgalaxy%2F

which, after login, will redirect you to https://repeatexplorer-elixir.cerit-sc.cz/galaxy/galaxy/ and that is 404
