This is now part of the usage instructions in the relative positioning
shared examples.

Since classes that include RelativePositioning no longer can override
low-level implementation methods to hook into internal details, this
means that catching query timeouts and other failures systematically is
no longer straightforward.

This change allows classes to implement a new callback hook:
`#could_not_move`, which is called with an exception if any of the
movement methods times out.

This involves custom handling for polymorphic models, and null-safety.

Hetrogenous sets of items need to override a couple of methods

These are tested by their behavior

By testing this, we can remove the tests on private members.

this comes at the cost of less-than-correct behaviour
