Fixes #1095

Description

This PR adds logging to well import if the well was assigned to a layer. This layer will not be used and the user is informed of that in the log. If the filter_top and filter_bottom properties are not present in the imported dataset, both a log message and an exception is generated, as we can't import the well with this information missing
