rpcclient, integration: Add test for getchaintips call
rpcclient now support calling the getchaintips rpc call. getchaintips_test.go adds test for the getchaintips rpc call. The test includes hard-coded blocks which the test will feed the node via rpc and it'll check that the returned chain tips from the getchaintips call are chaintips that we expect to be returned.
