WifiConfigStorLegacy: Add null check during restore

One of our OEM's is running into a crash in the config store migration
logic added in O. See the below bug for more details. This issue is not
seen on Pixel devices, because the |configKey| can never be null there.

Also, added a wrapper for IpConfigStore to help in mocking static
method in IpConfigstore.

Note: This code is pretty much unused on Pixel devices & other OEM's
who have upgraded from N to O. Only will help OEM's who upgrade from N
to P directly.

Bug: 73877225
Test: Unit tests
