Properly set skip_deleted and threading on Kolab storage IMAP operations (T1145)

Browse source 
Summary:
Fixes race-conditions between Kolab folders and Roundcube core
where skip_deleted/threading could be set for operations outside
of Kolab plugins, causing e.g. inability to see \Deleted messages.

Fixes T1145.
