Don't sure about russian guide: is this links meant to be for guide on russian, or not?
Added catch `\Throwable` to be compatible with PHP7.
Added it in cases where object state needs to be kept consistent.
Mainly on transactions but also some other places where some values are
reset before exiting.
Most of them could probably be refactored by using `finally` in 2.1, as
that requires PHP 5.5.

* Guide: Customizing Query Classes
Issue #12462
Clearly separate classes' definition.
Add information for default query condition with init().
Suggest using andOnCondition() instead of andWhere() as it didn't work
with the left join example provided.

Typos fixes
Add alias syntax to joinWith(), e.g. joinWith('author a').
No need to know the table name for defining an alias for the relation.
fixes#2377, alternative to #8788, which allows later implementation of
getting alias and column name ambiguation.
depends on #10813 to be merged first.
If using `all()`, the value of `$customer` will be an array of
`Customer` instances, not a `Customer` instance. Consequently,
```
$customer->unlink('orders', $customer->orders[0]);
```
will throw a PHP Fatal Error: Call to a member function unlink() on array.
