Fix autocomplete of migrateSystemVm

[vits-hugs]

Description

Right now, the autocomplete of the storageid parameter on the migrateSystemVm API is returning system VMs IDs instead of the expected storage IDs, as shown below. This bug also sets the CloudMonkey autocomplete cache for others APIs, such as migrateVirtualMachine.

This PR corrects this behavior by adding a verification so that the autocompleteAPI struct only changes its Name member to listSystemVms when it's defined to listVirtualMachines, thus not calling the listSystemVms API to autocomplete the storageid parameter.

How Has This Been Tested?

On CloudMonkey the autocomplete of all parameters in migrateSystemVm was called, and verified to be the correct answer, as shown below.

Tested manually. I verified that:

• Before the patch, storageid autocompletes to system VM UUIDs
• After the patch, storageid autocompletes to primary storage UUIDs
• After the patch, the other parameters (autoselect, hostid, virtualmachineid) were not affected
