[Compat] `StructureSpawn.renewCreep` throws when `undefined` is passed as the creep

[Hexcede]

When StructureSpawn.renewCreep is called with undefined as the creep value, it results in a runtime error in creep's checkCommon function.

Location of error in source (creep.ts)

This should have one additional check which ensures the creep value is defined, and if it isn't, it should return C.ERR_INVALID_TARGET as seen here (structures.js) in the original in-vm bindings, and here (creep.js) in the original intents processor.

Relevant stack trace:

Error: TypeError: Cannot read property 'my' of undefined
