isolateAndUnwrap now unwraps to a level determined by a target type
i.e. the type you are going to convert to.
Also in this commit wrap/unwrap/rewrap have been refactored to use
getLengthDifference. unwrap now takes an inner/outer unwrap depth.

The ve.Surface constructor was recently changed, but the instantiation
in the FormatAction tests was not updated accordingly.
The constructor now requires a ve.init.Target object.

I was seeing intermittent test failures caused by exceptions in
ce.SurfaceObserver (!!), seems to be caused by the FormatAction test
creating a surface but not destroying it.
