If input_case_insensitive_default setting is enabled, a case-sensitive simple query cannot be copied by URL

[arildm]

1. Start with the input_case_insensitive_default setting enabled
2. In the Simple search tab, the "case-insensitive" option will be checked by default
3. Uncheck the option and make a search; it will be case-sensitive
4. Reload the page (= copy the URL and open it anew)
5. Expected: the option is unchecked and a case-sensitive search is done
6. Actual: the option is checked again, and the search is case-insensitive

When the setting is enabled, we should use a different param: isCaseSensitive instead of isCaseInsensitive. This is how we handle the statistics_search_default setting in searchtabs.

Btw, this may be a good opportunity to update the param name to camel case: is_case_sensitive/is_case_insensitive.
