Console logged test results are mixed together

[BradBarnich]

Description

Console output for test results are being mixed together, causing mixed up colors incoherent output.

Steps to reproduce

dotnet test <the.sln> --no-build --filter "<a-filter>" --verbosity=normal

Expected behavior

Serial output of test results with consistent colors

Actual behavior

test results mixed together, causing colors to leak. Can see "Passed" is printed twice in green before the name of the test, and then following test names are written in green instead of white as they are supposed to be.
