0028081: Fix regression in HLR introduced by the fix for 28053

Browse Source 
The whole piece of the walking line between two vertices is no more checked for having length greater than Precision::Confusion(). Instead, only full duplicate points (comparing with gp::Resolution()) are removed, allowing the resulting line have any non-null length.

The test bugs modalg_6 bug27720_5 has been reverted to its original state.
