Alternative fix for crash displaying 'New Window' keymap item

rB870440dee910c9 just did NULL-check for Main pointer, actual issue is
that bContext pointer was NULL. This can be fixed by ensuring
PROP_ENUM_NO_CONTEXT flag is not set by calling
WM_operator_properties_sanitize when creating RNA buttons. Now, layout
previews are visible in keymap editor too.
