Call vacuum when cleaning the database
fix #3803: import from android wrongly enabled in history
refactoring: remove activity reference
Revert "Call vacuum when cleaning the database"

This reverts commit 5133e107e51e7e97f40644fc9dcad6a9ba42ac28.

Fix for #3827.
refactoring: avoid activity references
fix: don't show suggestion which cannot be found

Until now the owner display text was suggested when searching for the
owner. But the online search only searches for the user real name. E.g.
when a cache displayed "X and Y" as owner, the real owner is often only
"X".
change: set ownerUserId for OC caches

Some parts of our code expect this field to have some useful values.
Therefore don't leave it empty for OC caches.
