In case of error return non-zero value instead of cleaning up navigator. This
way main loop may do some more cleanup, or maybe even act differently.

This change effectively backs out f1737ddd06141afbe99f37af3b5c2d0f1df5fe7a,
implementing the same functionality in a simpler and more correct way.
Implementation details:
* imv_navigator.wrapped - a new field that has value "0" by default; once
navigator wraps around the list, this field recieves value "1".
* imv_navigator_wrapped(&nav) - a new function that returns non-zero value iff
navigator wrapped around the list. Currently just returns value of
imv_navigator.wrapped.
While at it, expanded "test_navigator_remove" and merged it with
"test_navigator_add". Resulting test is called "test_navigator_add_remove".
Fixes #94.

Test that removing items leads to predictable results. Right now test is fairly
incomplete, because it does not cover moving in reversed direction.

It was not fixed after imv_navigator_poll_changed() function was changed.
