The "Clear filter" function in list pages should not clear filters that are part of the sub-category

[Nicklas Nordborg]

This is a bit confusing for the user since the filter will no longer match the selected category.

References #2335: The "Clear filter" function in list pages should not clear filters that are part of the sub-category

Implemented a check in the "preset selector" code that changes the help text/tooltip when there is a filter on the sub-category column.

Fixes #2335: The "Clear filter" function in list pages should not clear filters that are part of the sub-category

It is fixed by first clearing all filters and then re-applying the sub-category filter. This means that the filter can change if it has been modified from the original filter.
