Title: Graph lasso cv fixes

Fixes all problems raised in issue #2159. This is a minor code modification.
**However** there will be some changes in the output values when a cross-validation object is provided as input: **every fold is now taken into account**, which wasn't the case before. Execution time will therefore increase for a number of folds greater than 3.
