When creating components for test server.

without the code, the serial number of power supply will be "To Be Filled By O.E.M." which will duplicate with other power supply.

How can this change be tested by a PR reviewer?

Added the tests in Test_ToComponentSlice by adding a new psu there with serial number as "To Be Filled By O.E.M" and test will catch it becomes 2 to prevent the duplicate.
