Quieter Integration Tests (#6513)

* Rename BaseLogger to WriterLogger to help the creation of other providers

* Don't export ColorBytes and ResetBytes from ColoredValues

* Make integration tests only print logs if they fail

* check can color before coloring

* I always forget about MSSQL

* Oh and use LEVEL in sqlite.ini

* Make the test logger log at info - as it means you see the router

* Remove empty expected changes

* Make the migrations quieter too

* Don't display SQL on error - it can be looked at in the file logs if necessary

* Fix skip when using onGiteaRun
