[BUG] Authentication fails in OpenAPI toolkit when using an Elitea secret instead of a direct password

[hrachsg]

Precondition:
An APi key has already been saved (e.g., for TestRail) in Elitea's secret.

Steps to Reproduce:

1. Open the Openapi toolkit or create a new one
2. Create a toolkit for the OpenAPI toolkit
3. Select Authentication type API Key
4. In the API key/password field, select Elitea Secret instead of providing a direct password
5. Save the toolkit and execute a tool from the OpenAPI toolkit

Actual Result:
Authentication fails when using an Elitea secret in the OpenAPI toolkit.

Expected Result:
Authentication succeeds when using an Elitea secret in the OpenAPI toolkit, the same as when providing a direct password.
