getPhoneLogs use wrong type of call log

Hi,
Today I tried to run the example code in a standard flutter emulator, and it failed with this log:

After a lot of investigation, it seems the invokeMethod doesn't really return what it should in its guts.

Fixed by #15

Sorry it took this long. We have better processes to monitor the code health in this repo now.
