test: serialize the peer colour cache suite

Browse Source 
The compute-count assertions read a process-global counter, and swift
testing runs a suite's tests in parallel by default, so one test
computing a colour between another's two reads would fail it for a
reason that has nothing to do with the cache. The seeds are unique per
test; the counter is not.

No other test touches _peerColorComputeCountForTesting, so serializing
this suite is enough.
