Make all the API calls queue together so we guarantee order

[Bug]           Some API calls were async hence the sync ones could have
                been run before them. There was no guarantee for the
                calls to be ordered the way they've been requested.
[Cause]         N/A
[Solution]      Add sync calls to the same queue as the async ones so we
                can guarantee their order of execution.
[Verification]  Built, installed, run tests.
