WDQS server names displayed without spaces

[egonw]

Describe the bug
The WDQS name is not shown correctly when using the new config, and spaces seem to get removed:

To Reproduce
Steps to reproduce the behavior. Update any SPARQL query with the following SPARQL-level config:

#sparql_endpoint = https://query.wikidata.org/sparql
#sparql_endpoint_name= WDQS main
#sparql_editurl = https://query.wikidata.org/#
#sparql_embedurl = https://query.wikidata.org/embed.html#

Note the name in the second line, which has the space.

Look up the aspect with the SPARQL query you changes, run the local server, and see how the space is dropped. (Also with multiple spaces in the EP name)

Expected behavior
The UI should include the space, as given in the config.
