Removed conflicts in
opm/core/wells/WellsManager.cpp
that were due to the change
```diff
- pd.well_index = WellsManagerDetail::computeWellIndex(radius, cubical, cell_perm, completion->getDiameter());
+ pd.well_index = WellsManagerDetail::computeWellIndex(radius, cubical, cell_perm, completion->getSkinFactor());
```
in WellsManager::createWellsFromSpecs which moved from WellsManager.cpp to WellsManager_impl.hpp file in a previous commit.
