If we have a many2many_tags widget that is writable then becomes
readonly, we can have in the code this chain of event:
- get list of widgets we need to reset some data for
- apply modifiers
- reset the widgets
but applying modifiers can delete a widget (eg. an editable field that
becomes readonly), so when resetting we could call code on a deleted
widget which caused an error.
For example, if we have an attribute:
`<field widget="many2many_tags" attrs="{'readonly': 'condition'}"/>`
if the field goes from editable to readonly and is affected by an
onchange, we will call `setIDForLabel` on the deleted instance of the
widget which will cause an error.
Added test without fix fails with error:
TypeError: Cannot read property 'attr' of undefined
at Class.setIDForLabel (/web/static/src/js/fields/abstract_field.js:324:35)
because as said, the function is called on the editable widget that is
removed and replaced with readonly widget at that point.
