Replacing kits for other MCU SDK is broken

QUL version - 2.8.0 (SHA - d8767cd8a8f966744914b376c48e9c1bf5ec6763)

When changing the MCU SDK path and selecting "Replace existing kits" option the kits are not replaced.

Steps followed:
1) Open QTC and go to Edit->Preferences->Kits (Observe screenshot 1)
2) Now go to Edit->Preferences->Devices->MCU
3) Change the Qt for MCUs SDK path to another valid MCU SDK path (Observe screenshot 2)
4) Click Apply
5) In the pop-up select "Replace Existing Kits" (Observe screenshot 2)
6) Then click OK - Here Again kit replacement Pop-up will be displayed which is not expected. Select "Replace Existing Kits" (The preferences window will close now)
7) Now go to Edit->Preferences->Kits (Observe screenshot 3)
8) Click on any MCU kit for details
9) Now check the CMake Configuration

We can then observe that the QUL_ROOT and QUL_GENERATORS path is still set to the previous MCU SDK version which is not expected. (Observe screenshot 4)
