check_array added to fit in iforest and ecod

[luismavs]

Hey,

For iforest models fitted with pandas Dataframes and then scored with decision_function() on pandas DataFrames, the following warning pops up:

xxxx/site-packages/sklearn/base.py:402: UserWarning: X has feature names, but IsolationForest was fitted without feature names

I have added very simple scikit learn utils check_array() to X in decision_function() to iforest (and ecod) models to suppress the warning.
