Update mod-kb-ebsco's title search (searching titles regardless of package) to use new parameter `searchType`

By default set this parameter to `searchType=Advanced` to reflect the current behavior in eHoldings application.

Remove existing `advancedsearch=true`

Update mod-kb-ebsco titles tests that are currently skipped (xit) pending this change

See below for more details:
https://developer.ebsco.com/guides/overviewsearch/

Of Note - title search within packages does not currently support this functionality
