* Update resolver to lts-13.29 and add lock file to repository
* Upgrade stack version
* Save cache after building dependencies only to have faster feedback loop when tests fail
* Move private functions from QueryBuilder to a separate Private module
* Move more functions over to private trying to make compilation consume less memory
* Split private in 4 modules
* Remove unused LambdaCase pragma
* Add profile to memory-tests.sh so it can find postgrest executable
* Move save dependencies before building and running tests for faster feedback loop
* circleci: Update stack versions from 1.1.2 to 1.9.3.
* circleci: Don't try to install unused packdeps and cabal-install.
* memory-tests: Rely on `stack build` to have been called already.
This happens in the previous circleci step.
