Check_MK Werk 1501: Legacy view formats created with 2014-09 snapshots are now converted

ID: 1501 Title: Legacy view formats created with 2014-09 snapshots are now converted Component: Multisite Level: 1 Class: Bug Fix Version: 1.2.5i7 Views which have been created with Check_MK snapshots from 2014-09 created the views in a legacy format which the current multisite code can not interpret. When an installation has such a view created by any user, ist ot usable anymore and shows an exception like "if 'service' in hide_filters and 'host' in hide_filters: TypeError: argument of type 'NoneType' is not iterable". This has been fixed now. The legacy views are now converted automatically. They are saved in the new format once the user makes his first change to this or another view.
