## Summary
This PR handles the case when there are multiple parameters with the
same name but different `options` and `displayOptions`. In this case, if
one of such fields is set, changing the dependent parameter value so the
other should be shown causes an error in case their options are not
compatible (this
[check](7806a65229/packages/workflow/src/NodeHelpers.ts (L786))).
#### Example:
LDAP node has two `options` properties with the same name:
1. `attributes` with predefined options (`add`, `replace`, `delete`).
Shown when **Update** operation is selected
2. `attributes` with a collection of `attribute` objects. Shows for the
**Create** operation
Setting one of these parameter values and switching operation so the
other is shown breaks the app.
This PR checks if there is a value saved for such parameter and removes
it before calling `getNodeParameters` in `valueChanged` handler.
