[BUG] Artifact Toolkit - Test Settings: create_file tool fails when previously filled field is cleared

[MarunNexit]

Description of Problem

When using the create_file tool in Test Settings section in Artifact Toolkit, if a user enters a value into a field and then clears it, the tool still includes that field in the outgoing request with an empty string ("").

This behavior exists across most tool fields, but it causes a critical issue in the create_file tool because it contains mutually exclusive fields: (These two fields cannot be sent together in the same request)

• filedata
• filepath

---

Steps to Reproduce

1. Open Artifact Toolkit -> Test Settings section.
2. Select the create_file tool.
3. Enter file name.
4. Enter a value in the filedata field.
5. Clear the filedata field.
6. Enter a value in the filepath field.
7. Execute the tool.
8. Inspect the outgoing request.

---

Expected Result

• The tool should execute successfully without triggering mutually exclusive field validation errors.

---

Actual Result

• Cleared fields are still included in the request as empty strings ("").
• Both filedata and filepath are sent together (one as "").
• The system returns an error indicating that both fields cannot be set simultaneously.

---

Additional Notes

• The issue becomes critical specifically for tools with mutually exclusive fields like create_file.
• Only reloading page/swithing tools help to clear the fields
