Somebody had forgotten "OC_User::setupBackends();"...

Added test cleanup listener to detect untidy tests

Fixed apps loading order

Made admin password field required on client side

fix preview for reshared file

Remove OC_DB_StatementWrapper::numRows()

Fix for case described in https://github.com/syncloud/owncloud-setup/issues/19

Using this method will result in an unneccesary extra SQL query (which also may
return an incorrect result because the underlying table changed in the
meantime).

In general:

If you are performing an UPDATE, DELETE or equivalent query,
OC_DB_StatementWrapper::execute() will already give you the number of
"affected rows" via \Doctrine\DBAL\Driver\Statement::rowCount(). This will
not work for SELECT queries, however.

If you want to know whether a table contains any rows matching your condition,
use "SELECT id FROM ... WHERE ... LIMIT 1".

If you want to know whether a table contains any rows matching your condition
and you also need the data, use "SELECT ... FROM ... WHERE ...", then use
one of the fetch() methods.

If you want to count the number of rows matching your condition, use use
"SELECT COUNT(...) AS number_of_rows FROM ... WHERE ...", then use one of the
fetch() methods.

On SQLite the app order can be arbitrary and cause strange bugs.
On MySQL, the app order seems to be always alphabetical.

This fix enforces alphabetical order to make sure that all environments
behave the same and to reduce bugs related to app loading order.

Fixes #6442

correctly mark app management active

After each test suite, detects whether there are stray datafiles, hooks
or proxies, then show a warning and clear them.

Removed numRows usage from encryption app

Added fseek fallback to the encryption app

numRows on Oracle always seem to return 0.

This fix removes numRows usage from the encryption and sharing app.

This fixes unit tests and potentially the encryption app itself
(migration status) when running on Oracle

Fetch all appconfig values for an app at once and cache the results

Don't use xcache in case admin auth is enabled

Finally kill mdb2 master
