Whilst extending TestSolrQueryResponse in
SOLR-8388 I noticed that getToLogAsString(String logid) returns "logidname1=value1 name2=value2 ... " instead of the "logid name1=value1 name2=value2 ..." indicated by its comment.
summary of changes in patch against trunk:
- Added space separator between logid and toLog values.
- Removed trailing space at the end.
- Added TestSolrQueryResponse.testToLog test case.
- Reviewed callers of the method and adjusted call arg for two of them.
