Bug: Boolean Attributes at Metaobjects doenst work after ex-/import

[admbzts]

We use a lot of metaobjects with boolean Attributes and if i export a metaobj with a boolean attribute and import it on an other metaobj_manager a boolean Attribute seems like a input type text on the instance of the metaobj. The same behavior with repository_manager. After saving the metaobj definition the boolean fields works correct.

On SS the left part is before a save, and the right part after a save.

We work around this in automated imports by

LOGGER.log(logging.INFO,
               f"resync meta attributes")
    self.unibe.content.synchronizeObjAttrs()

This may be time consuming depending on object and client model and is the same as saving in ZMI at tab system config > meta attributes.
